A novel ion exchange resin as an alternative for conventional chelates for separation and removal of toxic metal ions from industrial wastewater

Abstract

Tamarind Kernel-Power (TKP), a naturally occurring polysaccharide, has been used for the synthesis of a novel ion exchange resin, namely Tamarind triazine methyl sulphamic acid (TTMSA). The resin acts as a scavenger for toxic metal ions from the effluents of various industries. Characterization of resin has been done by FTIR, TGA and elemental analysis. Various physico- chemical properties of resin were analyzed including ion-exchange capacity, % nitrogen content, bulk density, bulk volume and moisture content. The resin was found to be stable with good reproducibility, good ion exchange capacity and selectivity for toxic metal ions. The partition coefficient values and percentage adsorption of various metal ions on the newly synthesized resins were determined by batch method with the help of Atomic Absorption spectrophotometer. The efficiency of resin was studied for up to 10 cycles. Analysis has shown that the adsorption of different metal ions on TTMSA resin followed the order Fe+2 >Cu+2> Zn+2>Pb+2>Cd+2. A suitable and cost-effective method was employed to reach the result of this experiment.
