Abstract

A method for the determination of S in plant materials is described. The material is oxidized by nitric and perchloric acid using a heating block to reduce perchloric acid loss. The SO₄ content of the solution is determined turbidimetrically as BaSO₄. The proposed method has been found to be more accurate and rapid than the conventional dry ashing procedures for the determination of S in plant material.
