A novel triolein-embedded activated carbon composite adsorbent was developed. 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.

Although Al-based coagulation and adsorption processes have been proved highly efficient for fluoride （F） removal, the two processes both generate large amount of AI（OH）3 solid waste containing F （Al（OH）3-F）. This study aimed to investigate the feasibility of utilizing AI（OH）3-F generated in AI（OH）3 adsorption （Al（OH）3-Fads） and coagulation （Al（OH）3-Fcoag） for the adsorption of cadmium ion （Cd（II））. The adsorption capacity of AI（OH）3- Fads and Al（OH）a-Fcoag for Cd（II） was similar as that of pristine aluminum hydroxide （AI（OH）3）, being of 24.39 and 1..90 mg·g^-1. respectively. The adsorption of Cd（II） onto AI（OH）a-Fads and AI（OH）a-Fcoag was identified to be dominated by ion-exchange with sodium ion （Na^＋） or hydrogen ion （H^＋）, surface microprecitation, and electrostatic attraction. The maximum concentration of the leached fluoride from Al（OH）a-Fads and Al（OH）3-Feoag is below the chinese Class-I Industrial Wastewater Discharge Standard for fluoride （〈 1.mg·L^-1.. This study demonstrates that the AI（OH）3 solid wastes generated in fluoride removal process could be potentially utilized as a adsorbent for Cd（II） removal.
