摘要
采用三电极电位法 ,对以苯酚 -四氯乙烷为溶剂测定聚酯中端羧基进行了实验和探讨 ,并建立了端羧基测定的新方法 ,此方法的相对标准偏差为 2 78% 。
In this paper,the method for determining the COOH in PET has been introduced by three electrode potential titration.The sample is solved in the solution of phenol tetrachloroethane.The condition and the parameter of the determination was discussed.The result shows that the relative standard deviation was 2 78% and the method can be applied to determine the terminal carboxy group in PET.
