In this research, carbon nanotubes modified with CNTs-Zn: ZnO@SDS/PEG@Ni2P nanocomposite (NCs) were applied for removal of methylene blue (MB) following its characterization by XRD, FESEM, and EDS-mapping techniques. Using central composite design (CCD), the relationship between operational parameters like sonication time (1 to 5 min), adsorbent mass (0.1 to 0.2 g), pH (3 to 11), and initial MB concentration (2 to 10 mg L-1) on the efficiency of the understudy system was optimized, and the maximum removal percentage of (100%) was found at 4.0 min sonication, 4 mg L-1 MB, 0.01 g of adsorbent, and pH = 9.0. The fitting of exptl. equilibrium data reveals that the Langmuir model (R2 = 0.995) is well suited for evaluating and representing the current adsorption system’s actual behavior. Kinetic analyses that match exptl. data at different periods show the pseudo-second-order model’s (R2 = 0.998) usefulness for properly describing exptl. data. Also, Pos. ΔH° and ΔS° readings, as well as neg. ΔG° values, imply an endothermic, phys., and spontaneous activity. The adsorbent’s reusability was also tested over six periods, with a minor decline in adsorbent capacity. In addition, this substance was tested in vitro for antibacterial activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) bacteria, addition, candida Albicans (C. Albicans) yeast, while exptl. results support the high efficiency of this composite for cleaning and safety improvement of water quality following its application as high-efficiency adsorbent. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Formula: C16H18ClN3S).
3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Formula: C16H18ClN3S
