title: Separation and determination of selenium(IV) and molybdenum(VI) in mixtures by selective precipitation with potassium thiocarbonate.
abstract: A simple method for the separation and determination of selenium(IV) and molybdenum(VI) in mixtures, based on selective precipitation with potassium thiocarbonate, has been developed. The procedure allows quantitative determination of 10-100 mg of selenium or 10-70 mg of molybdenum at pH 0.5-1.0. No interference by a wide range of other metal ions is observed.
