An analytical method was developed for the direct determination of microgram/liter concentrations of molecular H2S. The procedure involves bubbling compressed nitrogen through an aqueous sulfide solution to displace H2S which is collected in a glass bead concentration column and measured colorimetrically. The H2S concentration is calculated from the determined sulfide displacement rate and by reference to a log linear standard curve relating temperature with the H2S displacement rate to the H2S concentration in standard solutions. To permit accurate determination of H2S from the determined dissolved sulfide concentration and fraction of dissolved sulfide as H2S for specific conditions of temperature and pH, the apparent linear relationship between pK1 for H2S(aq) and temperature was defined. This procedure of calculating H2S in various waters and effluents was confirmed by the direct technique. The described analytical technique was used to define the relationship between test pH and sulfide toxicity to the fathead minnow.
