A novel MoS2@bentonite magnetic nanocomposite was synthesized for efficient removal of crystal violet from textile wastewater, showing high adsorption capacity and excellent reusability. The adsorption isotherm results were best fitted using the Freundlich model, indicating multilayer adsorption of crystal violet onto the nanocomposite.
Toxic dye effluents from textile wastewater can cause hazardous effects on human health. Hence, the removal of these effluents is crucial. In this study, a novel MoS2@bentonite magnetic nanocomposite (M-MoS2@bentoniteNC) was synthesized using a new, simple, and one-step process to remove crystal violet (CV). The samples of the M-MoS2@bentoniteNC were characterized using field emission scanning electron microscopy, elemental mapping with energy-dispersive X-ray analysis, transmission electron microscopy, selected area diffraction, Fourier transform infra-red spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, Barrett-JoynerHalenda and Brunauere-Emmette-Teller surface area analysis, thermogravimetric analysis, and vibratingsample magnetometry techniques. The synthetic M-MoS2@bentoniteNC exhibited a sufficiently large Langmuir maximum adsorption capacity towards CV (384.61 mg g(-1)) and remarkable reusability (92.55 % CV removal in the third adsorption-desorption cycle). The adsorption isotherm results were best fitted using the Freundlich model, which refers to multilayer adsorption of CV onto the M-MoS2@bentoniteNC.
