After soaking in dilute nitric acid, washed thoroughly with a water.
4 Flame Atomic Absorption Spectrometry
4.1 Determination of Range
Determination of zinc content in the range of 0.0003% to 0.050% (mass fraction).
4.2 Principle
Sample decomposition with nitric acid (when wZn < 0.0020 percent while that of lead generation lead sulfate precipitation), in a nitric acid medium, with air - acetylene fire
Flame atomic absorption spectrometer at a wavelength of 213.8nm, zinc measuring the absorbance when the sample contains a large amount of tin, antimony, adding EDTA, lemon
Citric acid, tartaric acid solubilization and prevent hydrolysis.
4.3 Reagents
4.3.1 tartaric acid.
4.3.2 citric acid.
