We report the preparation and application of a highly stable polymeric ionic liquid-modified electrode to immobilize ferricyanide for sulfide anal. Good long-term stability of the modified electrode verifies its potential in sensor applications. The electrocatalytic sulfide oxidation signal at â?.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 12.9nM (S/N =3) was obtained. Practical utility of the system is applied to the determination of sulfides in hot spring water and groundwater. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9Product Details of 915358-85-9).
1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9) belongs to imidazole derivatives. Imidazole is a heterocyclic compound with a five-membered planar ring. It is amphoteric and highly polar. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Product Details of 915358-85-9
