A selenious acid type solution of better performance was obtained by the test of polarization curve, the test of corrosion resistance and the test of duration life.
The Candida utilis has strong selenium enriching capacity and good stability, can be used for producing selenious yeast, and is a strain with high research and development value.
In this paper the electrochemical reduction mechanism of selenious acid(H 2SeO 3) in phosphoric acid solution was studied by rotating ring-disc electrode and cyclic voltammetry techniques.
