Flow injection fluorimetric determination of chromium(VI) in electroplating baths by luminescence quenching of tris(2,2′-bipyridyl) ruthenium(II)

A sensitive and selective luminescence quenching method is developed and used for manual and flow injection analysis (FIA) of chromium(VI) by reaction with [Ru(bpy) 3] 2+. The emission peak of ruthenium(II) at 595 nm is linearly decreased as a function of Cr(VI) concentration. This permits determina...
