The valence state analysis to determine selenide in mixtures of selenide, elemental selenium, selenite, and selenate compounds was devised by the selective volatilization of selenium as its hydride. As the optimum conditions of the reaction, 6 M (this unit is defined to 1 M=1 mol dm<SUP>−3</SUP> as below.) hydrochloric acid solution was dropped into the mixture and the hydrogen selenide gas generated was absorbed in a solution of sodium hydroxide and hydrogen peroxide. The optimal reaction temperature was found to be 170 °C for 40 min using nitrogen as the carrier gas. Utilizing this method, the fluctuation of the oxidation state of selenium was observed during the storage of zinc selenide samples.
