七氯七氯
  1. 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%;

    Results The recoveries of DDD , DDE , DDT , heptachlor and heptachlor epoxide in grains and vegetables ranged from 79.9 % to 112.3 % ;

  2. 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

    Determination of Heptachlor and DDT in Soil and Platycodon Grandiflorum by Capillary Gas Chromatography

  3. 河北表层土壤中七氯残留污染现状及其空间分异特征

    Contamination of Heptachlor in Surface Soil from Hebei

  4. 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。

    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 .

  5. 此法对用常规氧瓶法分别测定树脂中的硫和氯进行比较,七种树脂样品氯元素测定,五种样品的相对误差小于3%;

    The satisfactory results were obtained . This method was compared with the conventional oxygen flask method which determine S and Cl for chelate resin respectively .
