Abstract
A gas chromatographic method has been studied for the determination of hydrogen sulphide in anoxic waters. To suppress the escape and the oxidation of hydrogen sulphide in the water sample, either acetone or ethanol was mixed with the sample, and a small amount of hydroxylamine hydrochloride was added. The hydrogen sulphide in this solution was determined by gas chromatography. The proposed method is easy to perform and determination is possible for several days after the sampling. The limit of detection was about 0.1 ppm, the average of coefficients of detection was 9.2%.
