This standard specifies a method for the determination of nickel oxidation content in rare earth chloride and light rare earth carbonic acid by flame atomic absorption spectroscopy (AAS), suitable for the oxidation nickel mass fraction in the range of 0.0020% to 0.010%. The standard addition method is used to measure nickel Absorbance at a wavelength of 232.0 nm and calculate the nickel oxidation content by sample dissolving, heating and AtomicAbsorption Spectroscopy. The standard also details reagent and instrumentation requirements to ensure analytical accuracy and repeability.
