This paper describes a direct method for determining organic soil sulfur. By the proposed method the soil is ashed in an eletric tube-furnace at 800°C in a stream of oxygen and the escaping gases were absorbed by oxygen peroxide solution. After the ashing the excess of oxygen peroxide is eliminated by ebullition, and the resulting sulfate is determined by the colorimetric method based on the reaction with barium chloranilate, and the absorbance was determined at 308 milimicrons. The results obtained allowed to conclude that the tech nique proposed is good and the accuracy satisfactory.Downloads
