characteristics, and low specific gravity. Therefore, particular attention was provided to derivatization by immobilizing sulfhydryl onto the LC to solve these problems and increase the adsorption impact. The sulfhydryl group site generally has
elevated binding affinities with heavy metals due to its coordination and chelation.
