This part of GB/T 7739 specifies the use of inductively coupled plasma atomic emission spectrometry and inductively coupled plasma mass spectrometry A method of determining the amount of lanthanum in a gold concentrate. This section applies to the determination of the amount of strontium in gold concentrate, the measurement range. Method 1 is 20.0μg/g ~ 250.0μg/g; Method 2 is 0.5 μg/g ~ 50.0 μg/g. 2 Method 1. Inductively coupled plasma atomic emission spectrometry 2.1 Method summary The sample is decomposed by hydrochloric acid, nitric acid, hydrofluoric acid and perchloric acid, and is rich in polyurethane foam in the presence of hydrogen peroxide and iron salt in a mixed acid medium. Set, separate the ruthenium from the impurity element, and desorb it in a boiling water bath with a dilute nitric acid solution, selected by inductively coupled plasma atomic emission spectrometer Under the conditions, the spectral intensity of the lanthanum element in the test solution was measured at a wavelength of 190.801 nm, and the amount of ruthenium was calculated by a standard curve method. 2.2 Reagents or materials Analytically pure reagents and secondary deionized water were used in the analysis unless otherwise stated. 2.2.1 Hydrochloric acid (ρ = 1.19 g/mL). 2.2.2 Nitric acid (ρ = 1.42 g/mL). 2.2.3 Hydrofluoric acid (ρ=1.13g/mL). 2.2.4 Perchloric acid (ρ = 1.68 g/mL). 2.2.5 Hydrogen peroxide (30%). 2.2.6 Hydrochloric acid solution (1 9).
