The electrochemical response of a preoxidized nickel electrode to increasing additions of sulfide has been examined over temperature range from 25 to 70 °C. In the presence of sulfide a stripping like response was observed at all temperatures. The results detailed show that as the temperature is increased the sensitivity increases from 3.4 to 13.5 A M −1 for the determination of sulfide.
