热重法测定水解聚丙烯酰胺的水解度

The Determination of the Degree of Hydrolysis for Hydrolyzed Polyacrylamide by Using the Technique of Thermogravimetric Analysis

本文研究了利用热重法测定水解聚丙烯酰胺的水解度.测定结果与定氮法和电位滴定法作了比较,发现此法较后两种方法准确、简便.

In the present paper, the determination of the degree of hydrolysis for hydrolyzed polyacrylamide has been studied by using the technique of thermogravimetric analysis (TGA). The values measured by TGA was compared with that obtained from Kjeldabl method for nitrogen content and from potentiometer titration. It is found that the technique of TGA is more accurate, simple and convenient than others.
