In this work, beta-cyclodextrin-glycine-modified boehmite nanoparticles (BOH/Gly/βCD NPs) as an
efficient adsorbent were prepared and employed for the removal of crystal violet (CV) dye from aqueous
solutions. The results of study showed that the BOH/Gly/βCD NPs has a high adsorption efficiency
toward CV dye, and used in several adsorption-desorption cycles. In addition, the results indicated that
pseudo-second-order kinetics model and Freundlich isotherm model well describe the adsorption of CV
on the BOH/Gly/βCD NPs. The maximum adsorption capacity of CV dye was ۹۸ mg/g. The proposed
adsorbent has been successfully applied to remove model dye with satisfactory results.
