Abstract
New indicator reactions were proposed for the determination of selenium by the kinetic method based on the reduction of Methylene Blue by some sulfur- containing organic compounds. It was demonstrated that a high sensitivity o f the determination of selenium is attained using unithiol and thiomalic, 2 ,3-dithiomercaptopropionic, and rubeanic acids as reducing agents. In the p resence of unithiol, down to 4 ng/mL selenium can be determined.
