本文讨论了用胶体滴定法测定胺甲基化聚丙烯酰胺(APAM)阳离子度的原理和方法,提出了计算阳离子度的新公式,确定了测定条件和方法的测定准确度(≤1％)。
In this paper, the principle and method of colloid titration for the determination of the cationic degree of amine methylated polyacrylamide (APAM) are discussed. A new formula for calculating the cationic degree is proposed. The determination conditions and the determination accuracy (≤1%) of the method are confirmed.
