Earth chloride and light rare earth carbonate chemical analysis methods Part 10. Determination of manganese oxide content Flame Atomic Absorption Spectrometry1 ScopeGB/T 16484 provisions of this part of the determination of earth chloride and light rare earth carbonate, manganese oxide content. This section applies to the determination of earth chloride and light rare earth carbonate, manganese oxide content. Measurement range. 0.0020% to 0.20%.2 principle of the methodThe sample was dissolved in nitric acid in acid medium, with air - acetylene flame, using the standard addition method in atomic absorption spectrophotometer wavelength 279.5nm measured absorbance manganese, manganese oxide content is calculated in the sample.3 Reagents and materials3.1 Hydrogen peroxide (30%). 3.2 nitric acid (1 + 1). 3.3 HCl (1 + 1). 3.4 manganese standard stock solution.

Under optimum conditions the instrument, those who can reach the following indicators can be used. --- Characteristic concentration. measurement of the sample solution with the matrix phase in the same solution, wherein the sodium concentration is not more than 0.0062μg/mL. --- Precision. measuring the absorbance of the standard solution 10 times the highest concentration, the absorbance of the standard deviation does not exceed an average of 1.0%; most Low concentrations of the standard solution (not a zero standard solution) absorbance measured 10 times, and the standard deviation should not exceed the maximum average absorption solution 0.5% luminosity. --- Linear curve. The curve is divided into five sections according to concentration, absorbance difference between the absorbance difference between the highest and the lowest segment of the segment Ratio of not less than 0.7.5 Sample5.1 Preparation of rare earth chloride sample. A sample was crushed, quickly placed in a weighing bottle immediately weighed. 5.2 Preparation of light rare earth carbonate sample. weigh the sample immediately after the opening. Step 6 Analysis 6.1 Sample Table 1 sample was weighed, accurate to 0.0001g. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 16484.10-2009_English be delivered?Answer: Upon your order, we will start to translate GB/T 16484.10-2009_English as soon as possible, and keep you informed of the progress.
