Chemical Analysis Method of Zinc Concentrate
Determination of Germanium Content
Meiludsfur Chemistry of zinc oxides and their determination by atomic fluorescence spectrometry. This standard is used for the determination of zinc content in zinc concentrates. The determination range is 0.00050--3%. 2 Method Summary
The sample is dissolved in oxygen and nitric acid. 2% acetic acid is added to sulfuric acid medium. In the presence of hydride, the zinc is reduced by potassium hydride to form chromium. The chromium is introduced into a quartz atomizer with a gas phase and the intensity of the light is measured on an optical spectrometer. 3 Reagents
3. 1 Nitric acid (1. 42 g/a).
= 0.2% pyrolytic acid.
