Three gemini non-ionic surfactant-based polyethylene oxide with variable hydrophobic tails; 8 carbons (GPEOC), 12 carbons (GPEOL), and 16 carbons (GPEOP) have been synthesized successfully. The synthesized gemini surfactant regulated the preparation of the nano-catalyst AgNPs for toxic materials removal. The AgNPs were prepared via photo-chem. reduction reaction based on using the sun light and the gemini surfactants as reducing and capping agents, resp. The surfactant′s tail exhibited a substantial impact on regulating the AgNPs preparation as confirmed by TEM, UV-vis, and DLS measurements. The surfactant GPEOP produced AgNPs with a uniform, dispersibility and smaller particles size 14.8 ± 5.4 nm comparing to other two gemini surfactants GPEOC and GPEOL with shorter hydrophobic tail. The surface and thermodn. performance of the GPEOC, GPEOL and GPEOP gemini non-ionic surfactants were dependent on both solution temperature and surfactant′s tail hydrophobicity. The adsorption ability is significantly improved as functional of temperature or hydrophobicity. Elongation the surfactant′s tail and increasing the temperature, promote lowering the critical micelle concentration and enhance the adsorption affinity at interfaces. The study was extended to investigate how the surfactant′s tail improve the catalytic performance of the AgNPs-based catalyst. The surfactant′s tail controlled the catalytic performance of the AgNPs regarding the methylene blue and p-nitrophenol removal, where the GPEOP/AgNPs exhibited highest catalytic activity. Addnl., the surfactant′s tail controlled the antimicrobial of the prepared surfactant and surfactant/AgNPs hybrid system. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Name: 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride).
3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Name: 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride
