Popis:	The formation of a new tenary complex of molybdenum(VI) with 4-nitrocatechol (NC) and tetrazolium blue chloride (BTC), which is easily extractable from water into dichloroethane, is reported. The optimum extraction conditions (pH, concentration of the reagents, extraction time) and composition of the complex (Mo: NC: BTC = 1: 2: 1) were found. The spectrophotometric parameters of the extract were determined as well. Beer’s law is obeyed for concentrations of Mo ranging from 0.2 to 6.7 μg/mL with the molar absorptivity λ445 = 2.38 × 104 L mol−1 cm. A precise, sensitive, and simple method for determination of Mo in steels and ferromolybdenum was developed.
