4 Flame Atomic Absorption Spectrometry
4.1 Determination of Range
Determination of copper content in the range of 0.00050% to 0.60% (mass fraction).
4.2 Principle
Sample dissolved in nitric acid (when wCu<=0.0020%, lead to form lead sulfate precipitation and separation of copper). In acid medium, with air - B
Alkyne flame atomic absorption spectrometer wavelength 324.7nm measured absorbance of copper. When the sample contains a large amount of tin, antimony, plus Na2EDTA, lemon
Lemon and ammonium tartrate solubilization and prevent hydrolysis.
4.3 Reagents
4.3.1
disodium ethylenediaminetetraacetate (Na2EDTA).
4.3.2
ammonium citrate.
4.3.3
tartaric acid.
