Abstract

Fibrous adsorbents were prepared by carboxymethylation of waste textile fibers and were used for Cd(II) sorption in comparison with Dowex Mac-3 (DM-3). The prepared sorbents were designated carboxymethyl cellulose-Lyocell strands (CMC-LS) and carboxymethyl cellulose-Lyocell fabrics (CMC-LF). Kinetic and isotherm studies indicated that CMC-LS had the fastest sorption rate with high affinity constants and good column application potential. For the same packed column volume, CMC-LS reached ∼70% of its capacity whilst DM-3 reached ∼57%. 100% desorption was achieved using 0.1 M EDTA or HCl. This study therefore suggests a way to recycle waste fibers into adsorbents for treating heavy metal-polluted waters.
