Abstract:
N-o-Iodobenzoyl-o-tolyhydroxylamine has been synthesized and used as gravimetric reagent for direct determination of vanadium(V). The complex dried at 105-120 degrees has the definite composition VO(C(14)H(11)O(2)NI)(2)Cl. The method is simple, rapid, sensitive and selective and gives results reproducible within 0.1%. Precipitation is quantitative at room temperature over a wide range of acidity. The method is satisfactory for alloy steels and some rocks. The very low conversion factor (0.0632) is favourable for determining very small amounts of vanadium.
