Principle 3
Sample decomposition by alkali fusion, hot water extraction. Iron, titanium, cobalt, nickel and other elements and tungsten hydroxide precipitate was separated from the sulfuric acid - phenyl acetic acid - oct
Ning - potassium chlorate system, tungsten, a sensitive polarographic catalytic wave. On Polarograph starting potential of -0.5V (to calomel electrode as reference
Electrode), the peak potential of about -0.76V (saturated calomel electrode) at the pole with a spectrometer measuring peak current portion of derivative calculate the amount of tungsten.
4 Reagents
Unless otherwise stated in this section are consistent with the use of analytical reagent and GB/T 6682 analytical laboratory use in the analysis.
4.1 sodium peroxide.
4.2 ethanol.
4.3 sulfuric acid (11), Warning. Improper dilution can be dangerous
4.4 phenylhydroxyacetic acid solution (100g/L).
