摘　　要：利用玉米秸秆为原料,合成天然有机高分子两性絮凝剂,确定了最佳合成条件。实验结果表明,在原料粒径为0.15 mm,碱化时间为1 h,氢氧化钠质量分数为10%,反应时间为3 h,反应温度控制在90℃,合成出的天然高分子絮凝剂的絮凝效果最佳,处理效率可达到97%。In this paper natural organic polymer amphoteric flocculant was prepared by cornstalks and its optimum synthesis conditions were confirmed.The optimal conditions were achieved as follows:the grain size of cornstalks was 0.15 mm,the time of alkalization was 1 h,the concentration of Na OH was 10%,reaction time was 3 h,reaction temperature was 90℃.The results showed that the flocculant rate of synthesized amphoteric flocculant could reach 97%under the optimized synthesis conditions.
