摘要: We report here the preparation and application of a highly stable polymeric ionic liquid-modified electrode to immobilize ferricyanide for sulfide analysis. Good long-term stability of the modified electrode verifies its potential in sensor applications. The electrocatalytic sulfide oxidation signal at ∼0.0 V vs. Ag/AgCl in pH 7 PBS at the modified electrode was used for sulfide detection by hydrodynamic chronoamperometry and a detection limit of 12.9 nM (S/N=3) was obtained. Practical utility of the system is applied to the determination of sulfide content in hot spring water and ground water.
