The effectiveness of the water-soluble starch xanthate (SSX) process for removal of heavy metals [Hg(II), Cu(II), Cd(II) and Ni(II)] has been evaluated. Removal of Hg(II) and Cu(II) is effective; Cd(II) and Ni(II), less so. The metal [Hg(II)/Cu(II)] binding capacity remains the same in the pH range
Three types of starch derivatives containing amide groups were used in removal of heavy metal ions from their solutions. These starch derivatives were poly-(acrylamide) -starch graft copolymer, carbamoylethylated starch, and starch carbamate. The different factors affecting metal ion adsorption on t
