1 Scope
GB/T 14506 provisions of this part of the determination of the amount of vanadium silicate rocks.
This section applies to the amount of vanadium silicate rock Determination, also applies to the measurement of soil and stream sediments vanadium content.
Measuring range. polarography, 10μg/g ~ 800μg/g of vanadium. Spectrophotometry, 10μg/g ~ 2000μg/g of vanadium.
2 Normative references

Laboratory use specifications and test methods GB/T 6682 Analysis
GB/T 14506.1 Silicate rocks - Part 1. Determination of water adsorption
3 sulfuric acid - phenyl acetic acid - potassium chlorate medium polarographic indirect
3.1 Principle
Vanadium (Ⅴ) in slightly acidic benzene acetic acid - potassium chlorate solution under heating, to make benzene glycolic acid is decomposed into benzoic acid itself is also
Original generated vanadium (Ⅳ) were oxidized to potassium chlorate and vanadium (Ⅴ). Vanadium is not consumed only play catalysis. Time under controlled heating conditions,
Product diffusion current proportional to the concentration of benzoic acid and vanadium. On the oscilloscope Polarograph starting potential is -0.70V, half-wave potential that is derivative
Wave peak potential of about -0.96V (saturated calomel electrode). Determination of benzoic acid and thus indirectly reducing the current determination of vanadium content.
3.2 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.
3.2.1 sodium peroxide.
3.2.2 ethanol.
3.2.3 sulfuric acid (11), pure class distinctions. Warning --- improper dilution risk prone
3.2.4 sulfuric acid (19), pure class distinctions. Warning --- improper dilution risk prone
3.2.5 benzene glycolic acid solution (19).
3.2.6 potassium chlorate solution (60g/L).
3.2.7 Vanadium standard solution.
a) Vanadium standard solution (100.0μg/mL).
Weigh 0.1785g advance by 120 ℃ drying and high purity vanadium pentoxide dryer was cooled, placed in 150mL beaker
After added 5mL sodium hydroxide solution (100g/L), was dissolved in sulfuric acid (3.2.3) and 5mL excess and, shifted with water
1000mL volumetric flask and dilute to volume, shake, solution 1mL containing 100.0μg vanadium;
b) vanadium standard solution (10.0μg/mL).
Dispensing 50.0mL vanadium standard solution [3.2.7a)], placed in 500mL volumetric flask, dilute to the mark with water, shake, and this solution
