Abstract
The treatment of PVC with H2SO4 and H2O2 causes difficulties if the PVC contains lead or alkaline earths because of the precipitation of the corresponding sulphates. This precipitate can be dissolved with EDTA in ammonia. The procedure is fast and simple and the determination of calcium, aluminium and antimony by atomic absorption spectrometry give a good degree of accuracy.Keywords
