Glutamic acid-modified cellulose fibrous composite for adsorption of heavy metal ions from single and binary solutions

Abstract

New glutamic acid-modified cellulose is prepared and investigated as an bioadsorbent for simple and rapid removal of Cu2+ and Hg2+ from single and binary aqueous solutions. The effects of initial concentration of heavy metal ions, pH of solutions, temperature on the adsorption capacity of the bioadsorbent are investigated. Equilibrium studies demonstrate that the adsorption of Cu2+ and Hg2+ follows the Langmuir model in single aqueous solution system. Meanwhile, the adsorption kinetics has found to follow the pseudo-second-order model well. The competitive adsorption in the binary component system indicates the mutual inhibitation adsorption between the two metal ions. FTIR and SEM-EDS results reveal the Cu2+ and Hg2+ are successful adsorption on bioadsorbent by coordination and static electricity.
