Abstract  

Sulfite and SeS2O 62− reduce SeO 32− in acidic solutions to selenium. Selenandisulfonates are observed as intermediate products. They are separated by high voltage paper ionophoresis in acidic basis electrolytes and identified on the paper by application of35S- and75Se-labelled compounds. The formation of selenandisulfonates depends on thepH of the solution. In neutral systems species exist with up to 4 Seatoms in the chain, in acidic solutions species with up to 7 Se-atoms in the chain are found. Se7S2O 62− has been detected for the first time. Selenium precipitates by the decomposition of the selenandisulfonates with the longest chains.
