1 Scope
This section YS/T 227 specifies the method for determination of tellurium copper content.
This section applies to the determination of copper content in tellurium. Measurement range. 0.0004% to 0.0060%.
2 principle of the method
Sample dissolved in nitric acid, dilute nitric acid leaching of copper ions and most of the matrix isolation, air - atomic absorption spectrometer wave acetylene flame
Long 324.8nm at measuring the absorbance of copper, the standard curve method to calculate the amount of copper.
3 Reagents
Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity.
Nitrate 3.1 (ρ1.42g/mL).
3.2 nitric acid (11).
3.3 nitric acid (199).
3.4 copper standard stock solution. Weigh 1.0000g copper (≥99.95%), placed in 200mL beaker, add 15mL of nitric acid
(3.2), low-temperature heating to dissolve completely removing nitrogen oxides boil, cooled and transferred to 1000mL volumetric flask, 20mL of nitric acid was added
(3.2), dilute to the mark and mix. 1mL solution containing 1mg of copper.
3.5 Copper standard solution. Weigh 5.00mL copper standard stock solution (3.4) in 100mL flask, add 2mL nitric acid (3.2), with
Dilute with water to volume, and mix. This solution 1mL containing 50μg copper.
4 Instrument
Atomic absorption spectrometer, with copper hollow cathode lamp.
Under optimum working conditions for those who can reach the following indicators can be used.
--- Characteristic concentration. In line with the measurement of the sample solution matrix solution features copper concentration should be less than 0.025μg/mL;
--- Precision. standard solution with the highest concentration of 10 times the absorbance measurements, the standard deviation should not exceed the average absorbance of 1.0%;
With the lowest concentration of standard solution (not "zero" concentration of the standard) measuring the absorbance of 10 times, the standard deviation should not exceed the maximum
0.5% concentration of the standard average absorbance;
--- Linear curve. The curve is divided into five sections according to concentration, absorbance difference between the absorbance difference between the highest and the lowest segment of the segment
Ratio of not less than 0.8.
