This is Part 10 GB/T 4103's.
This Part replaces GB/T 4103.10-2000 "of lead and lead alloys - Determination of silver content", and GB/T 4103.10-
Compared to 2000, the main changes are as follows.
--- Additional fire assay Determination of silver content;
--- Measuring range extended from 0.0003% to ~ 1.5 to 0.0003% to 2.0%, by flame atomic absorption spectrometry - 0.0003%
Adjusted 1.5% to 0.0003% to 0.50%, measured fire assay ranges from > 0.50% to 2.00%;
--- Supplementary terms of precision.
The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized.

4 a method of flame atomic absorption spectrometry
4.1 Determination of Range
This method is applicable to the determination of lead and lead alloys in silver content. Determination of silver range 0.0003 to 0.50% (mass fraction).
4.2 Principle
The sample is dissolved in nitric acid, tartaric acid in dilute nitric acid medium, using air - acetylene flame atomic absorption spectrometer wavelength 328.1nm
Absorbance was measured at silver.
4.3 Reagents
4.3.1 nitrate (ρ1.42g/mL), pure class distinctions.
4.3.2 nitric acid (11).
4.3.3 nitric acid (13).
4.3.4 mixed acid. Weigh 30g tartaric acid dissolved in 200mL of water, 100mL added nitric acid (4.3.1).
