Desulphurization slag modified nickel slag adsorbent was prepared by unburned forming technology. The structure of the sample was characterized by BET,XRD,IR,SEM and EDAX. The adsorption performance of Pb~(2+) and Cu~(2+) onto the resultant adsorbent from aqueous solution was studied. Results indicated that the adsorbent possesses a network pore structure formed by the AFt and C–S–H through cross lapping; the adsorbent contains a large number of Si–OH and Al–OH functional groups. The presence of functional groups not only provides abundant adsorption sites for Pb~(2+) and Cu~(2+),but also improves the adsorption performance of Pb~(2+) and Cu~(2+) from waste water through the complexation of heavy metal ions. The result of specific surface area analysis showed that the adsorbent sample possesses mesoporous structure and the BET specific surface area is 27.15 m~2/g. The solution p H values for the adsorption of Pb~(2+) and Cu~(2+) were optimized to be 6 and 5.5,respectively. The adsorption capacities of Pb~(2+) and Cu~(2+) gradually increase,whereas the removal rates of the two metal ions decrease with increasing the initial concentration of simulated solution. The resultant adsorbent gives a higher adsorption capacity for Cu~(2+) than for Pb~(2+) in the single ion solution. However,it shows preferential adsorption of Pb~(2+) rather than that of Cu~(2+). Meanwhile,results of recyclability indicate the remarkable regeneration capacity,re-adsorption ability and reusability performance of the adsorbent sample.
