| 摘 要： | 对聚丙烯酰胺浓度的测定，使用最广泛的是淀粉一三碘化物比色法，其线性范围为0～6PPM，测量受温度影响大，重现性不够好。本文在此基础上改用了更优良的还原一掩蔽剂体系，使浓度检测的线性范围扩大到0～24PPM并且在室温下测定几乎不受温度影响，重现性好。

| Abstract: | A method for analyzing the concentration of polyacrylamide, which is based on the iodine-starch, is developed FeSO4, used as reductant and NH4HF2 as masking agent，the concentration of polyacrylamide may be determined within 0-24 ppm while by the old method within 0-6 ppm Especially, this method almost is not affected by the room temperature15-300C and has a better reappearance. |
