| 摘 要： | 以上海水稻土为样品,研究了不同伴随离子条件下土壤对铜盐的吸附解吸特性。结果表明:伴随阴离子为硝酸根、氯离子和硫酸根离时水稻土中对铜吸附量为硝酸根<氯离子<硫酸根。水稻土中对铜盐的解吸量为氯离子<硝酸根<硫酸根。

| Abstract: | Take the Shanghai paddy soll as the sample, the study was adsorption and desorption characteristics of copper with different accompanying anions. The results＇showed that：With the accompanying anions nitrate,chloride and sulfate ions, the adsorption capacity of copper was nitrate 〈 chloride 〈 sulfate in the paddy soils. The desorption capacity of copper was chloride 〈 ni- trate 〈 sulfate in the paddy soils. |
