Adsorption of Cu2+, Cd2+ and Pb2+ using polyacrylamide grafted brewer’s spent grain (BSG-g-PAAM) in aqueous solution was investigated. Sorption capacities for Cu2+, Cd2+ and Pb2+ were found to be 95.12, 87.45 and 84.65% respectively. The uptake of these metal ions were studied with the following parameters; PH, temperature, initial metal ion concentration, ionic strength and effect of contact time, in order to deduced the optimum condition for practical application of this adsorption material. The outcome indicated that metal ion sorption by BSG-g-PAAM decreased after temperature range of 49-52oC for these metal ions. Increase in ionic strength led to a decrease in sorption capacity. While increase in initial metal ion concentration showed an increase in adsorbate uptake. Optimal sorption capacity occurred at PH 4.0, 4.9 and 5.0 for Cu2+, Pb2+ and Cd2+ respectively. The result from this study demonstrated the ability of BSG-g-PAAM as a resource adsorbent material for the remediation of polluted streams.
