| Abstract: | A catalytic spectrophotometric method for the determination of trace vanadium is established based on the oxidation of chloromazine hydrochloride with potassium chlorate. The method shows high sensitivity and selectivity. Under optimum conditions, the detection limit is 2ng V/ml, the interference of other ions is discussed. The effect of temperature, acidity and concentration of reagents on the reaction speed is studied. In addition, the sensitivity of this method can be affected directly by the ability of oxidizer and the relationship between linear range of this method and temperature is also discussed. |
