Determination of zinc oxide content Flame atomic absorption spectrometry1 ScopeThis part of GB/T 6609 specifies the determination of zinc oxide content in alumina. This section applies to the determination of zinc oxide content in alumina. Measuring range. 0.0010%~0.040%.2 Principle of the methodThe sample was dissolved in a sealed container with hydrochloric acid at a constant temperature, and measured at an atomic absorption spectrometer wavelength of 213.3 nm using an acetylene-air flame. Its absorbance is used to calculate the amount of zinc oxide. When drawing the working curve, the interference of aluminum is eliminated by means of aluminum matrix compensation.3 reagents and materialsUnless otherwise stated, only reagents and secondary waters identified as superior grades were used in the analysis. 3.1 aluminum, w (Al) ≥ 99.99%, pre-washed with a small amount of nitric acid, and then washed with water to remove nitric acid, washed twice with absolute ethanol or acetone, Dry. 3.2 Hydrochloric acid (ρ=1.19g/mL). 3.3 Hydrochloric acid (2 1). 3.4 Aluminum matrix solution. Weigh 25.463g of aluminum (3.1) in a 1000mL beaker and add 360mL of hydrochloric acid (3.2). Place the beaker on a hot plate and slowly heat until completely dissolved. Remove the cooling, transfer the solution into a 500mL volumetric flask, dilute with water until the moment Degree, mix. 1 mL of this solution contained 0.1 g of alumina. 3.5 Zinc oxide standard storage solution. Weigh 0.1000g of zinc oxide [w(ZnO) ≥ 99.99%, pre-burn at 1000 °C for 1h, and dry Cool to room temperature in a desiccator, place in a 100 mL beaker, add 5.5 mL of hydrochloric acid (3.2), dissolve, and transfer to a 1000 mL volumetric flask. Dilute the water to the mark and mix. 1 mL of this solution contained 0.1 mg of zinc oxide. 3.6 Zinc Oxide Standard Solution. Pipette 50.00mL of zinc oxide standard storage solution (3.5) in a 500mL volumetric flask and dilute with water until engraved Degree, mix. 1 mL of this solution contained 0.01 mg of zinc oxide. Available when used.4 instruments4.1 PTFE sealed sample dissolver, device diagram see Appendix A. 4.2 Oven, rated temperature is not less than 350 ° C, temperature control accuracy ± 3 ° C. 4.3 Dryer, using fresh activated alumina as a desiccant. 4.4 Atomic absorption spectrometer with zinc hollow cathode lamp. Under the best working conditions of the instrument, the atomic absorption spectrometer that meets the following indicators Can be used. --- Characteristic concentration. in the solution consistent with the measurement solution matrix, the characteristic concentration of zinc oxide should be no more than 0.025μg/mL; --- Precision. 10 times absorbance measured with the highest concentration of standard solution, the standard deviation should not exceed 1.0% of the average absorbance; ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 6609.12-2018_English be delivered?Answer: Upon your order, we will start to translate GB/T 6609.12-2018_English as soon as possible, and keep you informed of the progress.
