摘要

Abstract

Herein a novel aminopropyl-containing ionic liquid based organosilica (ILOS-NH

) is prepared

characterized and applied as effective adsorbent for removal of crystal violet (CV) dye from wastewater. The ILOS-NH

material was synthesized by hydrolysis and co-condensation of 1

3-bis-(3-trimethoxysilylpropyl)-imidazolium chloride (BTMSPIC) under acidic conditions followed by treatment with 3-aminopropyl-trimethoxysilane in toluene under reflux conditions. This material was characterized using scanning electron microscopy (SEM)

diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS)

thermal gravimetric analysis (TGA) and energy dispersive X-ray analysis (EDAX). The material was effectively used in the removal of crystal violet at ambient temperature and showed high capacity and stability under applied conditions. The efficacy of pH

contact time

adsorbent dose

initial dye concentration

temperature

and isotherm studies and the applicability of pseudo-first

second order and Elovich kinetic models have also been investigated.
