✦ Synopsis

The application of silver(I1) as a powerful oxidizing reagent in flow injection analysis is described in detail. Under the experimental conditions, the half-life of the very unstable silver(II) was about 120 s. Nevertheless, various organic and inorganic substances could be determined. Spectrophotometric detection was at 390 nm where silver(I1) in nitric acid solutions absorbs strongly. As neither iron(II1) nor copper reacts with silver(II), oxidizable compounds can be determined in the presence of large amounts of these species. Special attention is given to manganese(II), which can be determined selectively by this method in the range 10-5-10~ mol 1-l.

Many reagents cannot easily be applied in quantitative analysis, because of their instability under atmospheric conditions. When such reagents are prepared in a flowing stream, their applicability is very promising; for example, in flow injection analysis, a reagent need be stable only for 20-30 s.
