Polarographic behaviour and determination of selenite and tellurite in simple solutions or in a binary mixture

  • Ahmed Hassan
Anorganische Und Physikalische Chemie


The polarographic behaviour of simple solutions of selenite and tellurite in 1M ammonium salts of formate, acetate, tartrate, oxalate, and benzoate solutions in absence and in presence of Triton X-100 as a maximum suppressor and a temperature of 25°C has been investigated. Schemes for the mechanism of reductions occurring at the DME have been deduced. A method for analytical determination of selenite and tellurite in simple solutions as well as in a binary mixture in the presence of 4–14·10−3% Triton X-100 is reported.

Polarigraphisches Verhalten und die Bestimmung von Selenit und Tellurit in einfachen Lösungen oder in binären Mischungen


Es wurde das polarographische Verhalten von einfachen Lösungen von Selenit und Tellurit in 1M Ammonsalzlösungen von Formiat, Acetat, Tartrat, Oxalat und Benzoat-Lösungen mit und ohne Triton X-100 als Suppressor bei einer Temperatur von 25°C untersucht. Es wurde ein Reaktionsschema für den Mechanismus der Reduktion an der DME abgeleitet. Eine Methode zur analytischen Bestimmung von Selenit und Tellurit in einfachen Lösungen und in binären Mischungen in Gegenwart von 4–14·10−3% Triton X-100 wird berichtet.
