Abstract

This study introduces a super-efficient gel adsorbent system (RRQG@CDC), synthesized by loading a flat-distributed polyquaternium gel (RRQG) onto a cyclodextrin carbide (CDC) skeleton. RRQG@CDC exhibits an adsorption capacity 1250 times higher than activated carbon, enabling highly efficient purification of dyeing wastewater. Its effectiveness remains consistent across varying pH and salinity conditions. Simulated scale-up tests confirm its feasibility for practical applications. A novel enhanced quasi-planar electrostatic adsorption mechanism is proposed, and the post-adsorption waste is shown to be reusable as high-calorific fuel, eliminating secondary pollution.
