Determination of sulphide in sediments and sewerage water by indirect conductometry

A conductometric method has been developed for the determination of sulphid e in sediments and sewerage water samples. The method is based on the separ ation of sulphide as hydrogen sulphide by treating the sample with sulphuri c acid The produced hydrogen sulphide was swept to an absorption solution o f copper sulphate with the help of a nitrogen stream The increase in the co nductivity of absorption solution was measured and plotted against sulphide concentration to obtain the calibration The effects of concerned parameter s were checked and the method was applied to the real samples of sewerage w ater and sediments.
