Frumina, N. S. published the artcileUse of p-nitrodiphenylamine as a redox indicator for determining chromium in the presence of vanadium, Application In Synthesis of 1821-27-8, the publication is Zavodskaya Laboratoriya (1969), 35(11), 1297-9, database is CAplus.

Cr was titrated with (NH4)2Fe(SO4)2 in 3-4N H2SO4 and in the presence of V (Cr:V > 3:1) with 0.1% p-nitrophenylamine in 1:1 H2SO4 as a redox indicator. For the determination of V the optimum medium is 8-18N H2SO4. The method is suitable for the determination of Cr in alloy steels.
