This standard applies to the determination of cobalt content in zinc concentrates, with a determination range of 0.0020% to 0.20%. Absorbance measurement of cobalt by light spectrum at 240.7 nm in dilute nitric acid medium after analysis of samples by flame atomic absorption spectroscopy (AAS) with muriatic acid, ammonium hydrogen fluoride and nitric acid. This method can be effectively applied to the analysis of cobalt content in zinc concentrates, providing accurate compositional analysis for metallurgy and related fields.
