摘　　要：用比表面积为1200 m2/g,平均孔径是3.7 nm的活性炭作为无机相,用丙烯酰胺作为有机相,制备多孔纳米聚丙烯酰胺-活性炭复合材料,并研究其对酚类化合物的吸附过程。结果表明,经聚合物修饰过的活性炭吸附能力增强,并以化学吸附为主,吸附容量随吸附时间、吸附剂量的增加而增加,最后达到平衡值,吸附过程更适合Freundlich等温吸附方程式。In this paper,we used activated carbon which has the specific surface area of 1 200 m^2/ g^-1 and the average pore size of 3.7 nm as the inorganic phase and acrylamide as an organic phase to prepare porous nano-polyacrylamide-activated carbon composite materials. Then we tested their adsorption ability of phenolic compounds, and we found that the adsorption capacity of activated carbon modified by the polymer increased which is mainly chemical adsorption. It increased with the adsorption time and the absorbent close increasing,and the adsorption process is suitable for Freundlich adsorption equation.
