The main objective of this study includes uptake of Cu (II) metal ions from waste water using biopolymers like Methyl Cellulose, Gum tragacanth and Hydroxypropyl methyl cellulose in parts per milligrams of polymer. The main intension of the study is to check the maximum possible absorption of heavy metal ions by using minimal quantity of bio-polymer sample from waste water. Removal of Cu metal ion from aqueous solution using Gaur gum [1] and Xanthan gum [2] has been reported earlier. This work includes sorption property studies, were conducted in order to determine the metal-polymer interaction in solution state. Effective uptakes of Cu (II) metal ions were analyzed at different concentrations at different temperature. Concentrations of each bio polymer samples were varied from 0.1mg (0.01%) upto 200mg (20%). Simple titration methods were applied to find out absorption of Cu (II) metal ion from waste water. pH of all polymer mixtures were maintained at neutral range of 6-7 throught the experiment. Certain parameters like density, viscosity, ultrasonic velocities were measured at different temperatures at different concentrations to study the interaction of the bio-polymers with metal ion. Change in density, change in viscosity, change in ultrasonic velocities were noted. All these parameters were found to decrease with increasing temperature. Spectrophotometric study revealed the absorption maximum for each polymer samples containing Cu metal ions. Maximum absorption for these bio polymers observed at 341nm.
