以淀粉和丙烯酰胺为原料，N，N‐亚甲基双丙烯酰胺为交联剂，采用水溶液聚合方法制备淀粉接枝聚丙烯酰胺（St‐g‐PAM ）凝胶，研究其对染料甲基橙的吸附作用。实验结果表明，制备得到的St‐g‐PAM 对甲基橙具有优良的吸附能力，其吸附行为符合Freundlich方程。同时，动力学研究表明，St‐g‐PAM 对甲基橙的吸附过程符合准二级动力学方程，初始吸附速率随着甲基橙初始浓度的增大而增大。

Taking starch and acrylamide as the raw materials , N ,N‐methylenebisacrylamide as the crosslinking agent ,starch‐g‐polyacrylamide hydrogel was prepared by aqueous solution polymerization . The adsorption of methyl orange by St‐g‐PAM was studied .The experimental results demonstrated that St‐g‐PAM was an excellent sorbent of methyl orange .The adsorption of methyl orange by St‐g‐PAM was Freundlich type .The adsorption kinetics followed the pseudo‐second‐order model .The initial ad‐sorption rate increased with the increasing of initial methyl orange concentration .
