In the present stuq.ies, ion exchange .p.rocess has .been used to r~move zinc :£Yomthe solution similar to effluent of textile industry using chelating ion exchange resin, Indion BSR'. Various parameters viz. contact time,'pH:of the -solution, resin dose etc have been studied for zinc recovery from the effluent. Extraction of zinc from the aqueous feed by Indion BSR resin was found to increase with increase in time, pH of the.soiution and resin dose. The data for adsorption of zinc with Indion BSR resin follows the Freundlich isotherm and second order rate equation. Pure zinc sulphate solution could be obtained by eluting zinc loaded resin with sulphuric acid. The raffinate could be disposed safely without affecting environment.
