Experiments were car-ried out in areas such as the preparation method, the char-acterization of physicochemical properties, and the adsorp-tion behavior of the composite adsorbent in removing diel-drin from aqueous solution. Results suggested that the novel composite adsorbent was composed of the supporting acti-vated carbon and the surrounding triolein-embedded cellu-lose acetate membrane. The adsorbent was stable in water, for no triolein leakage was detected after soaking the ad-sorbent for five weeks. The adsorbent had good adsorption capability to dieldrin, which was indicated by a residual di-eldrin concentration of 0.204 μg·L?1. The removal efficiency of the composite adsorbent was higher than the traditional activated carbon adsorbent. 关 键 词：饮用水处理 活性碳吸附剂 三油精 持久性有机污染物 吸附行为
