Hydrogen peroxide photometric analysis of titanium in vanadium alloy

The hydrogen peroxide photometric method for analyzing main constituent titanium in vanadium alloy were investigated in the paper, including the sample digestion method, chromogenic conditions, Lambert-Beer's law range, matrix interferences, method precision, recovery of standard addition, sample analysis and comparison analysis. The method precision in RSD% was 2.6%, the recoveries of standard addition were from 98.7%-99.4%. The experimental results indicated that the proposed method for determination of titanium in vanadium alloy was simple, fast, accurate, and easy to operate, which was suitable for quality control of vanadium alloy.
