OSTI ID:6984200
A method is proposed for simultaneous determination of sulfur, nitrogen, phosphorus, and halogens in fossil coals. The method consists in autoclave combustion of the sample in oxygen, absorption of the combustion products by a mixture of potassium carbonate and hydrogen peroxide solutions, and ion chromatographic determination of the anions formed.
