用胶体滴定法测定聚合物的电荷

Colloid Titration and Its Application in Charge Measurement of Polymers

研究了胶体滴定法测定聚合物的带电状况和测定条件。结果表明 :胶体滴定是一种方便、快速、准确的测定带电聚合物电荷密度的方法 ,能测定整个 pH值范围的带电聚合物的电荷密度 ,并讨论了影响胶体滴定测定聚合物电荷的因素。

In this paper colloid titration is studied. The results show that colloid titration is an easy, fast and accurate method to measure charge of polymers at all pH value. Some factors affecting the charge measurement are discussed. The study shows that the agents for colloid titration synthesized in the lab can be used and take the place of the important agents.
