Abstract
A method is described for the determination of dialkyltin salts leached from PVC into aqueous extracting media. The reagent used, 4-(2-pyridylazo) resorcinol, is stable and water soluble, but forms a chloroform-soluble complex with dialkyltin compounds. Indication of the screening efficiency of EDTA for possible trace metal contaminants is also given.Keywords
