Flow injection chemiluminescence determination of sulfide by oxidation with N-bromosuccinimide and N-chlorosuccinimide.
A rapid and sensitive flow injection chemiluminescence method is described for the determination of sulfide based on the chemiluminescence generated during its reaction with either N-bromosuccinimide (NBS) or N-chlorosuccinimide (NCS) in alkaline medium. The results of investigation of the sensitized and non-sensitized chemiluminescence reactions are presented. The emission intensity is greatly enhanced for both NBS- and NCS-sulfide chemiluminescence systems if dichlorofluorescein (for NBS-sulfide) and fluorescein (for NCS-sulfide) are presented in the reaction solutions. The methods were applied satisfactorily to the determination of sulfide in spring water samples.
