Study on the determination of vanadium and titanium in vanadium-titanium magnetite by ICP-AES

The conditions of analysis and determination of the elements vanadium and titanium in the vanadium-titanium magnetite by inductively coupled plasma atomic emission spectrometry (ICP-AES) were experimentally studied. The samples were dissolved in a closed high-pressure digestion tank, and the best analysis spectrum of the elements was selected The suitable working conditions of the line and the instrument are measured. The interference between the coexisting elements is very small. The relative standard deviation of the measured value is less than 2%. The recovery rate of the standard addition is between 95% and 105%. The analysis method is fast, simple, and the analysis result is accurate .
