This standard specifies the determination method of cadmium content in zinc and zinc alloys, with a determination range of 0.0005% to 0.500%. Absorbance of cadmium is measured at 228.8 nm by AtomicAbsorption Spectroscopy in dilute nitric acid medium after the sample has been analyzed by nitric acid. The standard also details the required reagents, standard solutions and instrumentation, and clearly specifies the measurement accuracy and working Linear dispersion linearity requirements to ensure the reliability and conformity of the measurement results.
