Determination of tin in the presence of lead by stripping voltammetry with collection at a rotating ring-disc electrode

Abstract

Stripping voltammetry with collection at a glassy carbon rotating ring-disc electrode is used for the determination of tin in the presence of lead. Tin can be readily determined at a level of 1 µM(0.12 µg ml^–1) in the presence of a 50-fold concentration of lead. Determinations down to 0.25 µM(0.03 µg ml^–1) are possible with prolonged deposition times (about 30 min).
