Abstract: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.
Keywords:three electrode potential titration  phenol tetrachloroethane  terminal carboxy group
