Abstract
This is a continuation of the study of the use of EDTA in ammonia solution to dissolve the precipitate formed when a sample of PVC with a high content of alkaline earths is attacked with sulphuric acid and hydrogen peroxide. The method is used to determine lead and magnesium, and is both rapid and reliable.
