Release of toxic methylene blue from water by mesoporous silicalite-1: characterization, kinetics and isotherm studies

Abstract In the present work, we have developed a mesoporous silicalite-1 using CMC as template for removal of MB from aqueous solution. The synthesized were characterized scanning electron microscopy (SEM), transmission (TEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), Energy-dispersive (EDAX) and N 2 adsorption–desorption isotherm (BET). XRD FT-IR confirmed formation crystallinity development MFI structure in silicalite-1. adsorption dye on was conducted by batch method. effect various parameters such adsorbent dosage, initial concentration, contact time temperature uptake ability investigated. operating maximum are dosage (0.1 wt%), (240 min), concentration (10 ppm) (30 ?). onto followed pseudo-second-order kinetic Freundlich isotherm. exhibits 86% efficiency even after six cycle. Therefore, is an effective eco-friendly environment.
