Abstract
A method is described for the trace determination of hydrogen sulfide, mercaptans, sulfides, and disulfides in industrial effluents which is based on a combination of head-space analysis with microcoulometry. This method increases the analytical sensitivity 10/sup 2/-10/sup 3/ times without any preliminary concentration of the sample. The factors affecting the precision and sensitivity of the analysis are studied. A simple device is developed permitting injection and gas chromatographic analysis of samples of the solution under study without losses of the compound of interest.
