泥炭吸附中重金属离子间的相互作用
he reciprocity of the combined ions in the adsorption of peat
本研究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，探讨吸附剂质量浓度、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。实验表明：随吸附剂量的增加，离子的去除效果提高；溶液pH=5时，泥炭对Cu2+、Pb2+均有最佳吸附效果；而pH=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+、Pb2+and the combined ions in this investigation. The effect of quality concentration of adsorption agent, the value of pH and the reciprocity of the combined ions on the capacity of the natural peat was discussed. The experiment indicated that: the removal of the ions was increasing with the advance of the quality concentration; the removal of Cu2+、Pb2+ was highest with pH=5; the removal of the combined ions was highest with pH=6. All indicated that the reciprocity exist between the combined ions.
