电导检测离子色谱法测定多聚磷酸盐

Determination of Polyphosphates by Gradient Elution Ion Chromatography Using Conductivity Detection

本文探讨用离子色谱电导检测法直接分离测定多聚磷酸盐，确定在ＡＳ４Ａ－ＳＣ色谱柱上分离正、焦、三聚、六偏磷酸盐混合物的最佳淋洗条件，并测定了浇铸料添加剂中多聚磷酸盐的含量。

Direct separation of polyphosphates by ion chromatography using conductivity detection was discussed in this paper.The optimum conditions for separation of ortho,pyro,tripoly and hexametaphosphates mixture was established.Content of polyphosphates in practical sample was analysed.
