Interactions of Cu2+,Ni2+and Humic Acid,Bentonite in the Water
水中Cu2+、Ni2+与腐殖酸、膨润土的相互作用研究

Interactions of Cu2+,Ni2+ on humic acid and the mixture adsorbent of humic acid and bentonite were studied.The effects of contact time,initial pH and temperature were determined.The removal rate of the metal ions increased with increasing contact time.The adsorption capacities increased with increasing temperature.Initial pH had a great impact on the removal rate of metal ions,when initial pH was around 7,the maximum removal rate can be achieved.Characteristics of adsorption kinetics of Cu2+,Ni2+ from aqueo...
