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 .

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 .
