Titrimetric microdetermination of certain sulphur-containing organic compounds by oxidation with alkaline potassium permanganate.
A titrimetric procedure is described for the microdetermination of some mercaptans and sulphur-containing amino-acids by oxidation with alkaline potassium permanganate at room temperature in presence of barium ions. The procedure can be applied to 0.002-0.025M solutions with an average deviation of 0.1-0.5%. The effect of variation in the amount of alkali and barium chloride and in the reaction period, on the stoichiometry of the oxidation reactions, has also been studied.
