本文采用酸/漂白液沉淀浊度法对检测聚丙烯酰胺浓度进行了试验研究,并分别测试了反应时间、试验温度、矿化度及三价金属离子对吸光度的影响,确定了测试条件,提出了干扰测试的因素及消除方法.试验结果表明,该方法的检测浓度范围宽、精度高,并可直接检测较高浓度的试样,是检测增粘水驱注采液中聚丙烯酰胺浓度的理想方法,可供现场参考应用. In this paper, the acid / bleaching solution sedimentation turbidity method for testing the concentration of polyacrylamide tested and tested the reaction time, test temperature, salinity and trivalent metal ions on the absorbance, determine the test conditions, put forward The factors that interfere with the test and the elimination method.The test results show that the method of detection of a wide range of concentrations, high precision, and can be directly detected higher concentration of the sample is to detect the viscosity of water flooding injection polyacrylamide concentration Ideal method for field reference applications.
