COMPLEX MOLYBDENUM OXIDE AND SYNTHESIS METHOD THEREOF Russian patent published in 2012 - IPC C01G39/02 

FIELD: chemistry.

SUBSTANCE: invention relates to complex molybdenum oxide of formula (VO)_0.09V_0.18Mo_0.82O₃·0.54H₂O, as well as synthesis method thereof. The complex molybdenum oxide of formula (VO)_0.09V_0.18Mo_0.82O₃·0.54H₂O can be used as electrode material for selective determination of concentration of vanadium (IV) in solutions containing vanadium (V). The method of producing complex molybdenum oxide of formula (VO)_0.09V_0.18Mo_0.82O₃·0.54H₂O involves preparation of a solution of molybdenum metal powder in aqueous hydrogen peroxide solution, addition of a sulphate hydrate to the obtained vanadyl solution in molar ratio Mo⁶⁺:V⁴⁺=1:0.5, followed by hydrothermal treatment of the mixture at temperature 140-170°C for 4-6 days, filtration, washing and drying.

EFFECT: disclosed mixed oxide of formula (VO)_0,09V_0,18Mo_0,82O₃·0,54H₂O with a hexagonal system in form of micro-rods, having ion-selective properties, can be used as electrode material for selective determination of vanadium (IV) ions in the presence of vanadium (V) ions.
