A glutamic acid-modified cellulose fibrous composite used for the adsorption of heavy metal ions from single and binary solutions

A new glutamic acid modified cellulose fibrous composite has been developed for Cu ²⁺ and Hg ²⁺ adsorption. The adsorption reaction follows a pseudo-second-order model, indicating the overall rates for the adsorption on GMC are controlled by chemical adsorption.
