摘要
采用氧化还原引发体系引发木薯淀粉与丙烯酰胺接枝共聚制备出天然木薯淀粉改性絮凝剂,用紫外-可见吸收光谱(UV-Vis)、红外光谱(FTIR)和拉曼光谱(RS)详细对比研究了木薯淀粉、丙烯酰胺和接枝共聚物三者的光谱特征,并据此讨论了接枝共聚机理。
Starch flocculent agent was prepared by grafting acryl amide onto starch with oxidization reduction reaction.The spectra of starch,acryl amide and starch flocculent agent were investigated by ultraviolet and visible spectrophotometry(UV-Vis),Fourier transform infrared spectroscopy(FTIR) and Raman spectroscopy(RS),and the graft mechanism was discussed according to the spectra results.
