制备了负载Ti/Fe腐植酸吸附剂，采用SEM、XRD等分析方法对负载Ti/Fe腐植酸的结构进行了表征，并对As(Ⅲ)进行了吸附性能的研究。结果表明，负载Ti/Fe腐植酸吸附剂较负载前的腐植酸，表面负载了大量类球状颗粒，内部孔道面积和表面积增加，活性吸附位点的数量增大，吸附能力有了明显的提高。在55℃、pH值为6、吸附平衡时间为120 min时，负载Ti/Fe腐植酸吸附剂对As (Ⅲ)有较好的吸附效果。负载Ti/Fe腐植酸吸附剂对As(Ⅲ)的吸附符合Freundlich吸附模型。

The humic acid adsorbent loaded Ti/Fe was prepared. The structure of the adsorbent was char-acterized by SEM,XRD etc. ,and the adsorption performance for As(Ⅲ) was studied. The result showed that a large number of spherical particles were loaded on the surface of the adsorbent,the internal pore size and surface area were increased and the quantity of active adsorption sites was improved. So the ad-sorption capacity of the adsorbent was promoted compared with the humic acid before loading. The humic acid adsorbent loaded Ti/Fe better adsorption effect for As (Ⅲ) when pH value was 6 and adsorption equilibrium time was 120 min at 55 ℃. The adsorption performance for As(Ⅲ) of the humic acid adsor-bent loaded Ti/Fe for As(Ⅲ) accorded with the Freundlich equation.
