摘要
通过玉米淀粉接枝聚丙烯酰胺（PAM）制成了新型复合絮凝剂S-g-PAM,进行了影响接枝共聚物合成的单因素实验和正交实验,以对高岭土悬浊液的絮凝性能为评价指标。结果表明,最佳合成条件为,m（玉米淀粉）∶m（PAM）=3∶0.001（质量比）,NaOH∶NaOCl=2∶3（体积比）,反应时间40 min,反应温度30℃,对高岭土溶液（110NTU）最佳去浊度效果为97%,投加量为30 mg/L。S-g-PAM使用的pH值范围为8~10,最佳温度范围20~40℃,与其它絮凝剂相比,其絮凝效果较好。
The new composite flocculant of starch-graft-polyacrylamide（S-g-PAM） was synthesized using starch and polyacrylamide as raw materials,the single element test,orthogonal test in the kaolin suspension were investigated.The results showed that the optimum conditions were as follows：the mass ratio of starch to PAM was 3 ∶0.001,the volume ratio of NaOH to NaOCl was 2 ∶3,reaction time was 40 min,reaction temperature was 30 ℃,the best removal rate of kaolin solution（110NTU） was 97%,and the added dosage was 30 mg/L.The optimum using range of pH value was 8～10,the best using temperature range was 20～40 ℃,compared with other flocculant,the flocculation effect of S-g-PAM was superior to others.
