1 Scope
YS/T 227 provisions of this part of the determination of tellurium arsenic content.
This section applies to the determination of tellurium arsenic content. Measurement range. 0.0002% to 0.0010%.
2 principle of the method
Conditions of use at a pH of 5.5 to 6.5, hydrolysis tellurium precipitated remove the bulk of the matrix, in hydrochloric acid medium, using a hydride - Original
Sub fluorescence spectrometer determination of arsenic content.
3 Reagents
Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity.
3.1 high-purity tellurium (mass fraction ≥99.999%).
3.2 nitrate (ρ1.42g/mL), pure class distinctions.
3.3 hydrochloric acid (ρ1.19g/mL), pure class distinctions.
3.4 nitric acid (11).
3.5 hydrochloride (11).
3.6 hydrochloride (19).
3.7 hydrochloric acid (595).
3.8 potassium hydroxide solution (200g/L). Weigh 40g of potassium hydroxide dissolved in 200mL of water stored in a plastic bottle, using now.
3.9 solution of potassium borohydride (20g/L). Weigh 10g of potassium borohydride were dissolved in 500mL of potassium hydroxide solution (5g/L), and now with the existing.
3.10 thiourea - ascorbic acid solution. Weigh thiourea in 300mL beaker, each 25g of ascorbic acid dissolved in water, the volume to
500mL volumetric flask, using now.
3.11 Storage arsenic standard solution. Accurately weigh 0.1320g trioxide (≥99.95%, pre-drying in a sulfuric acid desiccator to 24h
A) in the 300mL beaker, add 20mL of potassium hydroxide solution (3.8), completely dissolved by heating with hydrochloric acid (3.3) and to slightly cold
However, moved into 1000mL volumetric flask, dilute to volume, and mix. This solution 1mL containing 0.1mg arsenic.
3.12 arsenic standard solution. Pipette 5.00mL accurately arsenic standard stock solution (3.11) in 500mL volumetric flask, was added 75mL of hydrochloric acid
(3.3), dilute to the mark and mix. This solution 1mL containing 1μg of arsenic.
3.13 bromocresol purple - bromothymol blue mixed indicator. Weigh 0.01g bromocresol purple and bromothymol blue dissolved in 100mL
Water.
