摘要
以红薯淀粉为原料进行化学改性,合成了一种阳离子型高分子絮凝剂F4,并考察了各因素对合成的影响.研究结果表明,接枝共聚的最佳合成条件为:淀粉5g,引发剂0.35g,丙烯酰胺10g,反应温度50℃,反应时间3h.阳离子化条件为:氢氧化钠0.08g,阳离子醚化剂3g,反应温度70℃,反应时间2h.
Using sweet potato starch as raw material,a kind of cationic polymer flocculant F4 is synthesized.And the factors of affecting the synthesis process are investigated.The results show:the optimal synthesis conditions of graft copolymer are starch of 5 g,initiation agent of 0.35 g,AM of 10 g,reaction temperature of 50 ℃ and reaction time of 3 h.The conditions of cationization are NaOH of 0.08 g,GTA of 3 g,reaction temperature of 70 ℃ and reaction time of 2 h.
