摘要

为探讨Cu~(2+)对土壤溶出天然有机物(NOM)吸附特性的影响,本研究利用Modified Freundlich模型对不同Cu~(2+)浓度情况下NOM的吸附数据进行拟合分析。结果表明,四种工作液吸附数据与Modified Freundlich模型拟合的相关系数分别为0.901 8、0.949 5、0.900 5和0.957 6,说明该模型可以很好地表征Cu~(2+)对土壤溶出天然有机物的吸附特性;Cu~(2+)浓度对土壤溶出NOM吸附特性具有一定的影响,即活性炭对NOM的吸附强度随Cu~(2+)浓度增加呈现出先增加后减小的趋势。
        The investigation of Cu~(2+) effect on the adsorption characteristics of NOM derived from soil were conducted by fitting the adsorption data of four working solution with different Cu~(2+) concentration based on Modified Freundlich model. The results showed that the fitting correlation coefficient between adsorption data of four working solutions and Modified Freundlich model are 0.901 8, 0.949 5, 0.900 5 and 0.957 6, which indicated that the model can well describe the adsorption characteristics of NOM derived from soil; the concentration of Cu~(2+) has a certain influence on the NOM adsorption characteristics, that is, the adsorption strength of activated carbon on NOM increases first and then decreases with the increase of Cu~(2+) concentration.
