Department of Chemistry, College of Science, Raipur (M.P.) Department of Chemistry, Ravishankar University, Raipur (M.P.) Manuscript received 27 January 1976; revised 31 May 1976; accepted 15 July 1976 A method is developed for the spectrophotometric determination of vanadium(V) using N-­hydroxy-N, N'-diphenylbenzamidine as a new type of reagent. The procedure is selective and most of the common ions including Fe3+, Mo6+, Mn2+ and Cr3+ do not interfere. Vanadium in BCS steels is determined precisely and accurately
