中文摘要 |
介绍2甲4氯除草剂在3种不同有机质含量的土壤中吸附常数的测定。利用批量平衡法建立了Freundlich吸附等温线,获得2甲4氯在土壤中有机碳吸附常数为108.2甲4氯在土壤中是单分子层吸附,其吸附行为属于物理吸附。 |
英文摘要 |
A study on the adsorption of 2-methy-1-4-chlorophenoxyacetic acid (MCPA) on three different soils with different contents of organic matter was performed. Adsorption isotherms were obtained using batch equilibrium method, and adsorption constant were calculated. The value of organic carbon adsorption constant of MCPA in soil was 108. It is one molecular layer adsorption and belongs to physical adsorption. |
