Abstract
Copper and proton adsorption on gibbsite were determined at differing experimental conditions. The pHzpc of gibbsite was 8.70. As determined by the basic Stern-layer model (BSM), the optimized binding constants of electrolytic ions were KNa=−0.31 and KNO3=7.94. These parameters were coupled with the charge-distribution multi-site ion complexation (CD-MUSIC) model in quantifying copper adsorption by following reaction stoichiometry.(AlOH−1/2)2+Cu2+=[(AlOH)2 zCuw]+1 log K=7.15±0.7
