Determination of trace vanadium in organic solvents is studied by use of the oxidation of o-dianisidine with t-butyl hydroperoxide. The sensitivity of the catalyzed reaction is optimized by application of a modified simplex method. Under optimum conditions the detection limit is 0.7 ng V I&' in acet
