Abstract The gas sparging technique and a new gas-sensing electrode were evaluated for the determination of dissolved molecular hydrogen sulfide at environmentally significant concentrations in water. From the sparging experiments approximate coefficients were obtained for the distribution of hydrogen sulfide between nitrogen and distilled water, seawater, or municipal sewage effluent. In the latter medium the volatility of hydrogen sulfide was very much less than predicted from the pH-total sulfide relationship. The electrode, consisting of various semipermeable membranes, buffered electrolyte filling solution, silver-silver sulfide crystal sensor, and lanthanum fluoride internal reference electrode, gave a generally Nernstian response to more than 0.1 mg/l of molecular hydrogen sulfide. Various sources of the anomalous behavior were considered. The electrode is recommended for in situ measurements of molecular hydrogen sulfide at concentrations greater than 0.1 mg/l. More work is needed to make it useful at lower concentrations.
