The 1st line in footnotes should read * In the presence of 5 x 10-5 mol dm-3 Ag' and 1 mol dm-3 methanol not mol dm-3 Agl and 1* In the presence of 5 x 10-5 mol dm-3 methanol.

Flow Injection Catalytic Determination of Vanadium using the Indicator Reaction between Victoria Blue B and Bromate and A Citric Acid Activator

“…In the vanadium-catalyzed perphenazinebromate reaction", citric acid increased the sensitivity by a factor of 27 and enhanced the selectivity towards Fe 2+ and Cu 2+ . In vanadium-catalyzed chlorpromazine-bromate reaction 12 , tartrate enhanced the sensitivity by a factor of 23. Therefore, the activating effect of citric acid was tested.…”

“…The application of a catalytic method based on the oxidation of Bindschedler's green leuco base by bromate which had the detection limit of 0.008 ng ml" 1 in flow injection gave an insufficient detection limit (5 ng ml" 1 ) 12 been injected. The three merged zones react in the reaction coil for stopped-flow time as programmed, before passing into the flow cell.…”
