Abstract
In recent years, the widespread use of synthetic dyes in various industries has led to significant water pollution. The removal of these dyes from wastewater is crucial for environmental protection and human health. In this study, we reported the adsorption properties of β-cyclodextrin derived polymer networks (CDPNs) towards organic dyes and CDPNs showed exceptional high selectivity. An independent gradient model based on Hirshfeld partition of molecular density (IGMH) method was applied to figure out the mechanism of the high selectivity. The adsorption kinetics, and isotherms were investigated to understand the adsorption mechanisms. Comprehensive studies on the reusability of the adsorbent were conducted to assess its potential for practical applications. Overall, this study provides insights into the potential use of CDPNs as an effective adsorbent for dye removal.
