The atomic absorption method for the determination of vanadium is subject to many interferences from other elements. Interference suppression to coexisting elements such as molibdenum and tungsten by cupferron-methyl isobuthyl ketone (MIBK) extraction for the determination of vanadium has been examind. The most suitable range of pH values for the extraction of vanadium cupferate was less than 3. The organic extracts were aspirated directly to the flame as well as the aqueous solutions. The optimum experimental conditions are following : the analytical line is 3185A^^○ for vanadium, and the conbustion gas flow rates are 6.0 l/min for N_2O and 3.75 l/min for C_2H_2 with respect to the MIBK solution. This extraction method was efective to prevent the interference of molibdenum, but was of none effect for tangsten.
