Toxic metal ions such as Fe (II) and Hg (II) present in industrial waste water can be absorbed by certain biopolymers in parts per milligrams. Biopolymers like Guar Gum, Xanthan Gum, Acasia Gum, Gum Tragacanth, Sodium Alginate, Carboxymethyl Cellulose, Methyl Cellulose and Hydroxypropyl Methyl Cellulose were tested for the same. We found Hg (II) metal ion can be absorbed only by Xanthan Gum and Gum Tragacanth whereas Fe (II) metal ion absorbed by all these biopolymers from waste water. Maximum possible absorption of metal ions determined using minimal quantity of bio-polymer sample. Sorption kinetics and solution property studies of biopolymers conducted also sorption of Fe, Hg metal ions characterized at different temperature and concentrations of biopolymers. Absorption maximum for all these mixtures obtained through spectrophotometric study.
