Removal of pollutant from industrial effluent using ion – exchange resin

Agarwal, Preeti (2012) Removal of pollutant from industrial effluent using ion – exchange resin. BTech thesis.



Heavy metals are found as pollutant in industrial waste waters. Mainly it is originating from chemical anufacturing, painting and coating, extractive metallurgy, mining,nuclear, and other industries. Heavy metals exert a deleterious effect on the fauna and flora of lakes and streams. One of the potential remedies to this problem is the use of adsorption technologies. A resin named Tulsion A-23 is used for the removal of copper ion from water in this experiment. Aim of the experiment is to study the influences of various factors, such as contact time, pH of solution, initial adsorbate concentration, initial metal ion concentration and temperature, on the sorption and optimize their values. Experimental results show that resin had a good adsorption capacity for copper and could reduce the concentrations of copper in the wastewater. Suitable time for the operation is found to be 110 min. at solution pH of 6 with 400mg/L of resin and initial concentration of copper 60mg/L.Removal of copper at these optimized parameter is found to be 99.25 %. After that the removal of copper becomes practically very slow.The experimental data is well fitted with Temkin adsorption isotherm and follows second order rate kinetics.Based on these results we can conclude that it is possible to use this resin for removing copper from waste water.
