Extraction and Separation Studies of Tin(IV) with Tri-n-octylamine

Abstract
A selective method is developed for the separation of tin(IV) from copper, manganese, zinc, cadmium, mercury, nickel, lead, aluminum, bismuth, and molybdenum with tri-n-octylamine either from hydrochloric or acetic acid media. The metal ion from the organic phase is stripped with nitric acid solution and determined photometrically in the aqueous phase. The method is shown to be applicable to synthetic mixtures.
