摘要：

A flow injection method for the determination of sodium nitroprusside is described. It is based on the fact that nitrite ions can be released from sodium nitroprusside when the latter is treated with sodium hydroxide. The produced nitrite ions are quantified spectrophotometrically by diazotizing sulphanilamide and coupling with N-(1-naphthyl)ethylenediamine dihydrochloride. The optimized reagent concentrations as well as the flow injection system parameters are evaluated. The method is applied to a pharmaceutical preparation.
