Sorptive Removal of Cadmium Ions from Solution Phases Using Textile Fiber Waste Coated with Carboxymethyl Cellulose

Abstract:

This study investigates the possibility of applying textile fiber waste coated with carboxymethyl cellulose (CMC) as a feasible adsorbent for treating toxic heavy metals contained in wastewaters. The soluble CMC was successfully coated on Lyocell fiber and cross-linked with epichlorohydrin to give mechanical and water stability as well as to enhance its metal binding property. In a model wastewater solution, isotherm of cadmium sorption was modeled by the Langmuir isotherm model and predicted uptake exceeded 100 mg/g maximum. The developed sorbent could work effectively at very low concentrations and could be recycled many times. Equilibrium sorption was reached within 10~20 min of contact. The study may open a way to develop heavy metal adsorbents from waste textile, which by itself is inapplicable to sorption processes.
