Insight into the Deep Eutectic Solvent Extraction Mechanism of Flavonoids from Natural Plant

Deep eutectic solvents (DESs) are a new class of green solvents with potential applications for the extraction of target compounds from both liquid and solid samples. However, current research in the field has focused on demonstrating the advantages in extraction efficiency in terms of more extracted material and shortened time, while the mechanism of the increased efficiency has not been systematically studied. Herein, we explored the solvent and solute interaction mechanisms with the use of three extraction methods (heating, microwave-assisted, and mechanochemical extraction) and different types of DESs. Choline chloride (ChCl) was used as the hydrogen-bond acceptor, while hydrogen-bond donors used are malonic acid, methylurea, and glycerin. Flavonoids from Flos Sophorae were extracted. H-1 nuclear magnetic resonance (NMR) spectrometry, ultraviolet-visible (UV-vis) spectrometry, scanning electron microscopy (SEM), and ultrahigh-performance liquid chromatography (UPLC) analyses were performed to investigate the interactions between the flavonoids and the plant cell walls with DESs, and chemical reactions between the DESs and flavonoids. We also systematically evaluated the influence of several key factors on the extraction efficiency, which was consistent with the experimental results. The influence of DES in the sample on qualitative and quantitative UPLC analyses was systematically studied, and conditions were optimized. This study should provide insights into the interactions of specific DESs with various target compounds and help design more efficient extraction methods.

High-pressure HCl leaching of coal ash to extract Al into a chloride solution with further use as a coagulant for water treatment

In the present paper a novel process of the coal ash treatment was developed and analyzed: a high-pressure autoclave HCl leaching of the coal bottom and fly ash from an Omsk coal-fired power plant. This process was applied to extract aluminum from the coal ash into a chloride solution, which can further be used as a coagulant for water treatment. The Al extraction efficiency in this process can reach over 90% at certain process parameters discussed in the present study. Kinetics of the leaching process were evaluated using different kinetic (e.g. shrinking core) models. A semi-empirical equation was proposed for description of the kinetics of the leaching process as a function of the HCl concentration, solid-to-liquid ratio and temperature. Different mechanisms of the leaching process were also discussed and proposed. Water treatment by the obtained Al-chloride showed good results compared to an industrial coagulant; the treated water parameters were within the limits recommended by the World Health Organization for drinkable water.

Aerobic and Anaerobic Biodegradability of Organophosphates in Activated Sludge Derived From Kitchen Garbage Biomass and Agricultural Residues

Organophosphates (also known as organophosphate esters, OPEs) have in recent years been found to be significant pollutants in both aerobic and anaerobic activated sludge. Food waste, such as kitchen garbage and agricultural residues, can be used as co-substrates to treat the active sludge in sewage treatment plants (STPs). We investigated the biodegradability of nine OPEs derived from kitchen garbage biomass and agricultural residues under different conditions. Under anaerobic conditions, the rate of removal of triphenyl ester OPEs was significantly higher than that of chloride and alkyl OPEs. The addition of FeCl3 and Fe powder increased the rate of degradation of triphenyl ester OPEs, with a DT50 for triphenyl ester OPEs of 1.7-3.8 d for FeCl3 and 1.3-4.7 d for Fe powder, compared to a DT50 of 4.3-6.9 d for the blank control. Addition of an electron donor and a rhamnolipid increased the rate of removal of chlorinated OPEs, with DT50 values for tris(2-carboxyethyl)phosphine) (TCEP) and tris(1,3-dichloroisopropyl)phosphate (TDCPP) of 18.4 and 10.0 d, respectively, following addition of the electron donor, and 13.7 and 3.0 d, respectively, following addition of the rhamnolipid. However, addition of an electron donor, electron acceptor, surfactant, and Fe powder did not always increase the degradation of different kinds of OPEs, which was closely related to the structure of the OPEs. No treatment increased the removal of alkyl OPEs due to their low anaerobic degradability. Tween 80, a non-ionic surfactant, inhibited anaerobic degradation to some degree for all OPEs. Under aerobic conditions, alkyl OPEs were more easily degraded, chlorinated OPEs needed a long adaptation period to degrade and finally attain a 90% removal rate, while the rates of degradation of triphenyl ester OPEs were significantly affected by the concentration of sludge. Higher sludge concentrations help microorganisms to adapt and remove OPEs. This study provides new insights into methods for eliminating emerging pollutants using activated sludge cultured with kitchen garbage biomass and agricultural residues.

The Concrete Performance with Iron Tailings Sand Modified by Polypropylene Fibers under Aggressive Environment

This paper aimed to explore the performance of concrete with iron tailings sand modified by polypropylene fibers under aggressive environment. Three kinds of concrete (ordinary concrete, concrete with iron tailings sand (ITS), and concrete with ITS modified by polypropylene fibers) were exposed to drying-wetting cycles in 5% Na2SO4 solution for 28, 56, 84, 112, and 140 days. The performance, such as pores distribution, crack width, corrosion products, mass variation, expansion variation, compressive strength, flexural strength, and the diffusion of sulfate ion were measured at regular time intervals during the whole exposure period to describe the associated evolution laws. The results show that, in the process of the corrosion of sodium sulfate solution, the formation of gypsum and ettringite (AFT) has an important impact on the harmful pores (>0.1 mu m), cracks, mass variation, expansion variation, compressive strength, and flexural strength of the three concrete. Polypropylene fibers can refine the pores development and inhabit the crack development of the concrete with ITS, further alleviating the rate of sulfate ion attack on concrete and the rate of increase of corrosion products, so that the mass variation, the expansion variation, and the reduction of compressive strength and flexural strength can be limited effectively. Furthermore, in the concrete with ITS modified by 0.1% polypropylene fibers, the content of sulfate ions diffused is always the lowest.

Iron oxide nanoparticle synthesis using trigonella and tomato extracts and their antibacterial activity

Iron oxide nanoparticles (IONPs) were synthesised by combining the extracts of new plants (trigonella and tomato) with ferric chloride salt (FeCl3) via a simple chemical method at 200 degrees C for 2 hours. The biomolecules in the extracts play an important part in transforming FeCl3 to FeO NPs, which demonstrate antibacterial properties. IONPs were characterised via X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and Fourier-transform infrared spectroscopy (FT-IR). XRD revealed a crystallite size of 17 nm with a body centre cubic (BCC) structure (wustite) phase for FeO NPs made using trigonella extract. FeO NPs synthesised using tomato extract were 41 nm, and the diffraction peaks revealed a BCC structure phase with excellent crystal quality. FE-SEM images demonstrated that the average grain size of Fe2O3 without using any plant extract was approximately 31.36 to 125.5 nm, while for the FeO NPs using tomato extract, it was approximately 48.18 to 77.54 nm, and for trigonella extract, 27.91 to 40.94 nm. In the FT-IR spectra of IONPs with and without plant extract, a strong peak appeared at 699 cm(-1) for FeO NPs using trigonella extract and 655 cm(-1) using tomato extract. Antibacterial activity of IONPs was determined by growth inhibition zones of the gram-negative bacteria Klebsiellapneumonia and gram-positive bacteria Staphylococcus aureus. The growth inhibition zones for FeO NPs using trigonella extract were 42 and 47 mm, respectively. The zones for FeO NPs using tomato extract were smaller (30 mm and 35 mm, respectively). These NPs may be effective in healing infections caused by these bacteria.

Facile and rapid fractionation of bamboo wood with a p-toluenesulfonic acid-based three-constituent deep eutectic solvent

Here, we report a strategy with the application of p-toluenesulfonic acid (p-TsOH) based three-constituent deep eutectic solvent (3c-DES) for the efficient fractionation of bamboo wood towards its main components. Three kinds of deep eutectic solvents (DESs), including choline chloride (ChCl)/ ethylene glycol (EG)/p-TsOH, tetrabutylammonium chloride (N4Cl)/EG/p-TsOH and tetrapmpylammonium chloride (N3Cl) /EG/ p-TsOH, were facilely prepared and assessed for the pretreatment of bamboo wood. ChCl-EG-p-TsOH (molar ratio of 1:0.5:1) was found to be the most effective, evidenced by more than 93.36% xylan and 90.32% lignin removals with most of the cellulose (86.73%) retained in the pretreated bamboo in a short time of 10 min at 100 degrees C and a 10 wt. % solid loading, which significantly improved delignification by more than 85% compared with that of using ChCl-EG (molar ratio of 1:2) as a two-constituent at the same conditions. The 3c-DES pretreatment resulted in the desirable deconstruction of the recalcitrant of cell walls in woody biomass, evidenced by the higher glucose yield of 90.2% by the enzymatic hydrolysis of the cellulose-rich substrate, which was nearly four-fold higher than that of the untreated bamboo. The extracted lignin showed high purity (95%) with a moderate and homogeneous molecular weight, showing promising potential applications in the downstream production of biochemicals and biomaterials. Furthermore, the 3c-DES exhibited excellent recoverability by evaluating the fractionation efficiency and enzymatic hydrolysis performance with the recycled DES. The results from this study demonstrated that p-TsOH-based 3c-DES showed practical significance for the fast and effective fractionation of woody biomass for high-quality components.
