Two OSW SW-846 methods used for the determination of sulfide have been modified to include the use of sulfide specific ion electrodes (SIE). Currently in both methods sulfide is converted to hydrogen sulfide and distilled into a scrubber solution for subsequent determination by iodometric titration. In the modified methods, the hydrogen sulfide in the scrubber is determined by sulfide SIE. A single lab evaluation was performed to determine the operating characteristics. The sulfide SIE is linear over the range 0.25-6000 mg/L sulfide with a detection limit is about 0.2 mg/L sulfide. Over the range 5-6000 mg/L, the relative precision of the SIE is 2-4 percent. The accuracy (expressed as percent recovery) over the range 0.25-6000 mg/L varies from 75-103 percent. The sulfide SIE is very selective for the sulfide dianion and in the scrubber solution, there are no interferences. Recoveries in real samples spiked with 17.5 mg/L sulfide varied from 68-77 percent before distillation and 93-98 percent after distillation. The results from the evaluation indicate that the sulfide SIE provides an alternate technique to determine sulfide in environmental samples after distillation.
