抄録

Practical problems concerning the application of our previous spectrochemical method to routine industrial analysis were studied. The differences and variation of the components between sponge titanium sample solution and spectrochemical standard solution of titanium tetrachloride and hydrochloric acid, and the evaporation of impurity elements during dissolution of titanium sponge were negligible. The time trend of Si% in spectrochemical standard solution was found by observation of relative intensity for 6 months, and its correction procedures are proposed. Various physical properties of carbon electrodes for spectrochemical analysis were determined. The effect of the quality of carbon electrodes on the analytical accuracy and precision was described. Finally, some procedures for expanding the analytical range are described.
