摘要: Ultramicro amounts of selenium in sulphuric acid are determined by a new atomic absorption spectrophotometric method. Selenium(IV) is directly ater extraction into toluene with an aromatic o-diamine and addition nickel(II) prior to atomization; the determination total (0, IV VI) needs treatment sample selected oxidizing reducing agents.
