| 摘 要： | 采用室内测试方法,研究了低浓度的外源铜离子在两种不同性质土壤中的吸附、解吸过程及其受邻苯二胺的影响。结果发现,外源铜离子在红壤中的吸附随pH的变化明显变化,而在黑土中的吸附则随pH变化改变较小,吸附在红壤中的铜较吸附在黑土中的铜更易于解吸。有机物邻苯二胺对铜在两种土壤中的吸附和解吸过程产生了明显影响,酸性条件下邻苯二胺的存在增加了红壤对铜的吸附量,但同时也增加了铜的解吸百分数。而邻苯二胺基本不改变铜在黑土中的表观吸附量,但显著影响铜的解吸百分数。

| Abstract: | Adsorption and desorption processes of copper ions in two soils were studied. The results showed that pH influenced Cu adsorption behavior more significantly in red soil than that in black soil. Effect of o-phenylenediamine on Cu behavior in two soils was investigated. It has been indicated that the percentage adsorption and desorption of Cu in red soil increased in the presence of o-phenylenediamine. Although o-phenylenediamine did not change the adsorption quantity of Cu in black soil, it affected Cu adsorption process strongly, raveling from the different Cu desorption percentage in black soil in the presence of o-phenylenediamine. |
