| 摘 要： | 报道了草甸黑土中5种酞酸酯类化合物的吸附作用．吸附试验结果表明土壤对PAES吸附为线性吸附，吸附系数（Koc）随着PAE的溶解度增加而减少，淋溶试验结果表明5种PAE的淋溶性质各不相同，DMP、DEHP、DOP仅在0～15cm土层检出，表现出较低的淋溶性，而DEP、DBP则表现出较强的淋溶性．

| Abstract: | The adsorption of five kinds of phthalic esters by loam clay was studied in this paper.The results from experiments indicate that it is a linear adsorption when soil adsorb the phthalic esters.The coefficient(K_(oc)) of adsorption reduced as the solubility of the phthalic ester increased.The results from experiments indicate that the eluviation of the five kinds of phthalic esters having nothing in common with each other.DMP,DEPH and DOP were detected only in the depth from 0 cm to 15cm in the soil,they exhibit a lower eluviation,whereas DEP and DBP exhibit a stronger eluviation. |
