A procedure has been developed for the determination of tin in high-purity zinc and zinc die-casting alloys present in amounts from 0.001 to 0.2%. The samples are dissolved in sulphuric acid, oxidized with hydrogen peroxide, precipitated with cupferron, redissolved and reduced, and finally the tin is determined polarographically. By this method, the tin can be determined with an accuracy of ± 2.0% when present in amounts less than 0.005%. A method is now available for the routine polarographic determination of trace amounts of copper, lead, cadmium, and tin in high-purity zinc and zinc die-casting alloys with a high degree of accuracy and precision.
