Direct gravimetric determination of molybdenum(VI) in presence of other ions and its application to alloy steel.
N-o-Toluoyl-N-o-tolylhydroxylamine has been synthesized and employed successfully as a gravimetric reagent for direct determination of molybdenum(VI). The dried complex (110-120 degrees ) has definite composition, MoO(2)(C(15)H(14)O(2)N)(2). The method is quite simple, rapid, sensitive and gives reproducible results. The precipitation is quantitative at room temperature over a wide range of acidity. The reagent is highly selective and the method is satisfactory for analysing alloy steels.
