| Abstract: | This paper investigated the decomposition conditions of p-Fluoropolystyrene and established a new method for determination of fluorine in p-fluoropolystyrene by ion-selective electrode analysis. The recovery per cent of the standard addition of p-Fluorobenzoic acid for this procedure equals 99.9%, the relative standard error is 2.72%. This new method has of the advantages of brief and high accuracy. |
