Über das auftreten von symmetrischem tellurandiselenandisulfonat im verlauf der umsetzung von tellurit mit selenotrithionat

Abstract

Reduction of TeO₃ ²⁻ by SeS₂O₆ ²⁻ in acidic solution gives a black mixture of Se and Te. Intermediary products are SeSO₃ ²⁻; [O₃S−Se−Te−Se−SO₃]²⁻ and Selenandi-sulfonates, containing 1–4 Se-atoms in the chain. The anions are separated by high voltage paper electrophoresis and identificated radiochemically, using³⁵S−,⁷⁵Seaand¹³²Te labelled reactants of detected specific activity. For the formation of the anions the reduction of TeO₃ ²⁻ by SeSO₃ ²⁻ is discussed.
