Abstract:

In this work, beta-cyclodextrin-glycine-modified egg shell nanoparticles (ESh/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 ESh/Gly/βCD NPs has a high adsorption efficiency toward CV dye, and used in several adsorption-desorption cycles. In addition, the results indicated that pseudosecond- order kinetics model and Freundlich isotherm model well describe the adsorption of CV on the ESh/Gly/βCD NPs. The maximum adsorption capacity of CV dye was ۹۵ mg/g. The proposed adsorbent has been successfully applied to remove model dye with satisfactory results.
