3 Method summary

The sample was dissolved with hydrobromic acid, hydrochloric acid, and hydrogen peroxide. The hydrochloric acid-hydrobromic acid volatilized to remove tin and bismuth. In a dilute hydrochloric acid-hydrobromic acid medium, The absorbance of zinc was measured with an air-acetylene flame at an atomic absorption spectrometer wavelength of 213.9 nm.

4 Reagents
