本文用分光光度法对高矿化水中微量聚丙烯酸的测定进行了研究。探讨了地层水中各种离子对测定的影响及其消除方法,确定了较好的测试条件。方法简便、灵敏,不需要复杂的分析仪器,便于油田及工厂监测和控制使用。在矿化度近于60克/升的模拟油井水中,聚丙烯酸浓度为1-30ppm时变动系数小于5%。 In this paper, the determination of trace polyacrylic acid in mineralized water was studied by spectrophotometry. The effects of various ions in formation water and their elimination methods were discussed, and the better test conditions were determined. The method is simple, sensitive and does not require complex analytical instruments for monitoring and control of oilfields and factories. In simulated well water with a salinity of nearly 60 g / l, the coefficient of variation of polyacrylic acid at 1-30 ppm is less than 5%.
