| 摘 要： | 探讨了用淀粉- 碘化镉法测定部分水解聚丙烯酰胺(H PAM)质量浓度时, 淀粉质量浓度对测定结果准确性的影响。实验发现溶液吸光度不仅受聚丙烯酰胺质量浓度的影响, 而且也受淀粉质量浓度影响。随着直链淀粉质量浓度增大, HPAM 溶液的最大吸光度也在增加。采用了新的溶解淀粉方法, 考察了最佳淀粉剂量, 并给出改进后的测定方法。利用改进后的方法建立的HPAM 质量浓度- 溶液吸光度(Abs)标准曲线, HPAM 质量浓度在0～ 25 mg /L , 标准曲线呈极好的线性关系, 测定值的相关系数R2 为0. 999 8 。 |

| Abstract: | The effect of mass concentration of starch on accuracy of determining partially hydrolyzed polyacrylamide(HPAM) concentration by use of starch-cadmium iodide method was studied.The results show that the Abs not only increases with the increase of HPAM mass concentration,but also with the increase of straight chain starch mass concentration.A way to improve the solubility of straight chain starch was adopted and the best added quantity of starch was found.The improved process for determining HPAM mass concentration was displayed.In the range from 0 to 25 mg/L of HPAM mass concentration,a standard working curve of HPAM mass concentration vs.solution absorbency was constructed with R2 is equal to 0.999 8. |
| Keywords: | Aydrolyzed polyacrylamide Straight chain starch Starch-cadmium iodide method Branch chain starch |
