Methods for chemical analysis of rare earth concentrates Part 5. Determination of the amount of alumina Inductively Coupled Plasma Atomic Emission Spectrometry1 ScopeGB/T 18114 provisions of this part of the determination of rare earth concentrates in the alumina content. This section applies to the determination of rare earth concentrates in the alumina content. Measuring range. 0.50% - 8.00%.2 principle of the methodSample with sodium hydroxide, sodium peroxide decomposition melted, remove thorium and rare earth separation of alkali, using matrix effect correction method in an acidic solution, at Argon plasma spectrometer for measuring the amount of alumina.3 Reagents3.1 sodium hydroxide. 3.2 sodium peroxide. 3.3 hydrochloride (ρ1.19g/mL). 3.4 hydrochloride (11). 3.5 standard aluminum stock solution. Weigh accurately 0.1000g high purity (purity > 99.99%), add water, 5mL and 10mL hydrochloric acid (3.3), Low heat to dissolve, removed, cooled to room temperature and transferred to 100mL volumetric flask, dilute with water to volume, and mix. This solution containing 1mL 1mg aluminum. 3.6 aluminum standard solution. accurate Pipette 5.00mL aluminum standard stock solution (3.5) in 100mL flask, add 2mL of hydrochloric acid (3.4), Dilute with water to volume, and mix. This solution 1mL containing 50μg aluminum. 3.7 Argon. [w (Ar) > 99.99%].4 Instrument4.1 Full Spectrum Direct Reading plasma emission spectrometer. 4.2 source. argon plasma light source, power is not less than 1.0kW.5 SampleThe sample size should be 5.1 to grind through the 0.074mm sieve. 5.2 The sample was 105 ℃ ~ 110 ℃ drying 2h, placed in a desiccator to cool to room temperature. Step 6 Analysis 6.1 Sample Weigh 0.5g sample (5), accurate to 0.0001g. 6.2 Determination of the number of Weigh two samples (6.1) parallel determination of the mean value. 6.3 blank test ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 18114.5-2010_English be delivered?Answer: Upon your order, we will start to translate GB/T 18114.5-2010_English as soon as possible, and keep you informed of the progress.
