【Abstract】 A method for the determination of vanadium in waste vanadium catalyst by inductively coupled plasma optical emission spectrometry(ICP-OES)was developed.The sample was dissolved with mixed acid of hydrochloric acid nitric acid hydrofluoric acid and perchloric acid and the content of vanadium in waste vanadium catalyst was determined by ICP-OES.The optimum sample dissolution method and the optimum conditions of the instrument were determined by this method.Under the selected operating conditions,the detection limit of vanadium is 0.006μg/mL.The relative standard deviation(RSD,n=11)less than 1%and the recovery rate is 98.9%—101%.This method can be used to determine the content of vanadium in waste vanadium catalyst.The process is short and easy to operate with satisfactory results.更多还原
