| 摘 要： | 研究了铜、锌在双城、海伦、方正农田黑土中的吸附解吸行为.3地土壤吸附Cu2+、Zn2+的量均随着平衡液中Cu2+、Zn2+质量浓度的增加而增大.双城、海伦、方正农田黑土对Cu2+的吸附解吸行为用Freundlich方程拟合最佳,吸附态Cu2+的解吸有明显滞后现象,而且3地土壤吸附态Cu2+的解吸率均较低.供试土壤对Zn2+的吸附行为用Freundlich方程拟合最佳,而对Zn2+的解吸行为用Langmuir方程拟合最佳. |

| Abstract: | An experiment was conducted to study the adsorption-desorption characteristics of copper and zinc in phaeozem farmland soils in Shuangcheng,Hailun and Fangzheng of Heilongjiang Province. Cu2+ and Zn2+ amounts adsorbed by the phaeozem farmland soils enhanced with the initial concentrations of Cu2+ and Zn2 in equilibrium liquid increasing. The adsorption-desorption process of Cu2+ in the phaeozem farmland soils could be well expressed by Freundlich equation,and desorption of the adsorbed Cu2+ had an obvious l... |
