摘要
Proposed is the technique of spectrophotometric determination of sulfide in the range 0.05-1.50 mg/dm(3) based on oxidation of it in the sulfate medium by the known excess of bromate followed by subsequent oxidation of N,N-diethylaniline in the presence of the excess of bromide and photometering at 226 nm of 4-bromo-N,N-dietylaniline being formed. The sulfide detection limit constitutes 0.03 mg/dm(3). Metrological characteristics of the technique were checked by way of determination of sulfide in waters in ballneotherapy (mud, silt, etc.).
