| 摘 要： | 以玉米淀粉为原料，经磺甲基化、接枝共聚反应，合成具有磺甲丙烯酰胺基团的改性淀粉（SMAS），红外光谱结果表明，淀粉成功的被接枝。通过吸附平衡实验研究在不同吸附温度、吸附时间和pH值的条件下，SMAS对铜离子Cu（Ⅱ）的吸附情况。结果表明，SMAS吸附铜离子的时间短，适用温度范围宽，当pH值6.1，温度298K，30min时SMAS对铜离子的吸附量为4.828mg／g。

| Abstract: | The sulfomethyl acrylamide modified starch(SMAS) was prepared by means of sulfomethylation and graft copolymer reaction of corn starch.The structural analysis of SMAS was determined by IR.It was concluded that the starch was grafted successfully.The various conditions of SMAS against copper ion was investigated by absorption equilibrium experiments,such as temperature,time and pH value.The results show that the absorption reaction of copper ion is fast and is wide extent on temperature.The suitable conditio... |
