摘　　要：用稻壳制备出比表面积为1 100m2/g,平均孔径为3.8nm的活性炭作为无机相,用乙酸乙烯酯作为有机相,制备纳米孔聚丙烯酸-活性炭复合材料,并测试其对染料的吸附。结果发现经聚合物修饰过的活性炭吸附能力增强,而且以化学吸附为主,不会随时间延长而导致被吸附物质脱落。Firstly, we prepared husk--based activated carbon used as the inorganic phase, which has the specific surface area of 1 100m^2/g and the average pore size of 3.8nm,and polyvinyl acetate used as the organic phase. Then we prepared composite materials of pdycrylic acid--activated carbon and tested their adsorption ability for dye. We found that the adsorption capacity of activated carbon modified by the polymer increased,which is mainly chemical adsorption,and it would not loss the dye with time.
