Determination of metals in poly(vinyl chloride) by atomic absorption spectrometry. Part 2. Determination of lead and magnesium in samples of poly(vinyl chloride) with a high content of alkaline earths

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 r...

Descripción
Sumario: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.
