Abstract The use of pyroaurite type sorbents for removal of Cd(II) from aqueous solution has been studied. In batch tests, the sorbents IRA, PTS, PAC, PLC, FeO(OH) and RH could remove 95.3 ,93.8 , 93.9, 90.4, 75.1 and 59.5% cd (II) at initial metal concentration 0.1 mg/l, pH 6.0, temperature 25°C, agitation time 5 h, sorbent dose 5 g/l and rpm 150. The order of cadmium removal capacities for these chemical adsorbents was found to be: IRA > PTS > PAC > PLC >FeO(OH) > RH. The effects of various parameters affecting the adsorption such as initial metal concentration. Sorbent dose, contact time and pH were determined. Adsorption decreases with in cadmium concentration and pH but increases with increase in adsorbent dose and contact time. Equilibrium was attained in 5 h and the maximum removal was at pH 8. Thus, basic medium favoured the removal. The sorption data fitted very well to the Langmuir isotherm as well as the Freundlich equation.
