天然泥炭对Cu^(2+)、Pb^(2+)吸附性能的研究

Study of Natural Peat Adsorption about Cu^(2+) and Pb^(2+)

以天然泥炭为吸附剂,对Cu2+、Pb2+及其混合离子溶液进行吸附实验,探讨了泥炭质量浓度、溶液pH值、混合离子间的相互作用等因素对吸附剂性能的影响.实验结果表明:泥炭用量的增加,提高了离子的去除效果;当溶液pH值为5时,泥炭对Cu2+、Pb2+均有最佳的吸附效果;而当pH值为6时,泥炭对混合液离子的去除率最高,表明离子间存在一定的相互作用.

Natural peat was used for the adsorption of Cu2+ and Pb2+ and the combined ions.The effect of quality concentration of peat,the value of pH and the reciprocity of the combined ions on the capacity of the adsorption agent was discussed.The experiment indicated that:the removal of the ions increases with more amount of peat,the adsorption of Cu2+and Pb2+ was highest with pH of 5,and the removal of the combined ions was highest with pH of 6,which indicates that the reciprocity exists between the ions.
