摘　　要：以木屑纤维素为基体,采用球磨法,制备负载铝氧化物的纤维素(C-Al),研究其对水中砷离子(As)的吸附行为。探讨不同吸附条件对C-Al的吸附影响,研究结果表明,C-Al对As有良好的去除效果,当溶液的pH为3~7,投加量为2 g/L,反应温度为25℃,As初始浓度为200 mg/L,C-Al对As的吸附容量高达62 mg/g。cellulose loaded with aluminum oxide(C-Al) was prepared by ball milling with wood sawdust cellulose in the presence of the Al-oxide at room temperature around 25℃. The adsorption characteristics of arsenic ion(As) in aqueous system was studied.The adsorption capacity of C-Al toward As ions reached as high as 62 mg/g when the pH of solution was 3~7;while the dosage of cellulose adsorbentwas 2 g/L;and the initial concentration of As was 200 mg/L.
