Spectrometer for Determining Zinc Content
Atomic Absorption Spectrometry (AAS) is a widely used analytical technique for the determination of zinc concentration in a variety of samples. This method involves sorption of Zn 2+ as 4- (2-amino-3-hydroxypyridine-4-yl-azo)1,5-dimethyl-2-phenyl-1,2-dihydro-pyrazol-3-one (AHDDO) onto. Zinc is refined by calcinating the ore to form zinc oxide, which is then reduced with carbon (dry reduction method) or dissolved in sulfuric acid and subjected to electrolytic eduction (wet reduction method). Calibrate the instrument each time a set of samples is analyzed nd check calibr printer output while aspirating each sample.
