GB/T 8151.14-2012 《Methods for chemical analysis of zinc concentrates - Part 14： Determination of nickel content - The flame atomic absorption spectrometric method》 Related products

Part 14 of this standard specifies a method for the determination of nickel content in zinc concentrates, suitable for samples with nickel content ranging from 0.0030% to 0.050%. The determination process involves dissolving the specimen with muriatic acid, nitric acid and sulfuric acid, followed by separation of nickel by trichloromethane extraction and butanedione oxime complex. Finally, in muriatic acid medium, the nickel Absorbance was determined using an air-acetylene flame and AtomicAbsorption Spectroscopy at a wavelength of 232.0 nm. The standard requires the use of analytical purity reagents and water of corresponding purity to ensure the accuracy of the determination.
