A titrimetric method for the determination of sulphate in fertilisers

Abstract

A method is described for the determination of sulphate in fertilisers in which the sulphate is precipitated with barium chloride from an acidified EDTA solution. The precipitate is filtered off by using membrane filters and is dissolved in ammoniacal EDTA; the excess of EDTA is then titrated against a solution of magnesium ions with Eriochrome black T as the indicator. No interference is encountered from iron, aluminium, fluoride or phosphate ions.
