Copper and copper alloys -
Determination of tin content. Part 10
Method 1 a Zeeman effect electrothermal atomic absorption spectrometry
1.1 Scope
This method specifies the method for determination of copper and tin in copper alloy content.
This method is applicable to the determination of copper and tin in copper alloy content. Measurement range. 0.0001% to 0.0020%.
1.2 Principle of the method
Sample was dissolved in nitric acid, a volume of the test solution injected into the electrothermal atomizer with Zeeman effect atomic absorption spectrometer
224.6nm wavelength measuring the absorbance of tin, calculated tin content by working curve method.
1.3 Reagents
Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity. experiment
The utensils were soaked 12h, washed thoroughly with water and nitric acid (1.3.4).
1.3.1 Copper (Cu mass fraction ≥99.99%, tin content of < 0.00005%).

--- Low precision requirements. the highest concentration of standard solution, the absorbance measured 10 times, calculate the mean and standard deviation. The standard
Standard deviation should not exceed 1.5% of the average absorbance. The lowest concentration of standard solutions (not zero concentration standard solution
Solution), 10 times the absorbance measured, calculating the standard deviation. The standard deviation should not exceed the average absorbance of the highest concentration of the standard
0.5% of the value.
1.5 Sample
Sample processed into crumb-like.
