摘　　要：采用淀粉-碘化镉法测定部分水解聚丙烯酰胺(HPAM)的浓度,确定最佳测定条件为:醋酸钠缓冲溶液pH值5.0、溴代反应时间10 min、溴水/KBr加入量1 mL;并探讨了淀粉浓度对测定结果的影响,结果表明,淀粉浓度为5.0 g.L-1时,测定结果较好。The determination of concentration of partially hydrolyzed polyacrylamide by starch-cadmium iodide method was studied.The optimum conditions were obtained as follows：sodium acetate buffer pH value 5.0,the bromination reaction time 10 min and the addition amount of Br2/KBr 1 mL.The results showed that the absorbance increased with the straight chain starch concentration,and the determination result was best when the straight chain starth concentration was 5.0 g·L-1.
