Determination of Heptachlor and DDT in Soil and Platycodon Grandiflorum by Capillary Gas Chromatography 毛细管气相色谱法测定土壤和桔梗中七氯及滴滴涕的含量
Contamination of Heptachlor in Surface Soil from Hebei 河北表层土壤中七氯残留污染现状及其空间分异特征
The adsorption rate, equilibrium adsorption capacity and removal efficiency of heptachlor on CA-T were higher than that of heptachlor epoxide, which might be attributed to the stronger hydrophobicity of heptachlor. 该复合吸附剂对亲脂性较强的七氯具有较快的初始吸附速率、较大的平衡吸附量和较高的去除率。
Results The recoveries of DDD, DDE, DDT, heptachlor and heptachlor epoxide in grains and vegetables ranged from 79.9% to 112.3%; 结果粮食、蔬菜中有机氯农药滴滴滴(DDD)、滴滴伊(DDE)、滴滴涕(DDT)、七氯和环氧七氯的回收率在79.8%~112.3%;
