Determination of potassium chloride and potassium sulfate potassium content X-ray fluorescence spectrometry1 ScopeThis standard specifies the method for determination of potassium chloride and potassium sulfate potassium (K2O) content using wavelength dispersive X-ray fluorescence spectrometer. This standard applies to potassium chloride and potassium sulfate potassium (K2O) content determination. Measurement range (mass fraction) are shown in Table 1. Table 1 measurement range potassium chloride and potassium sulfate potassium content Sample type Measurement range (mass fraction) /% Potassium chloride 53.07 ~ 63.18 Potassium 38.61 ~ 54.052 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. JJG810 wavelength dispersive X-ray fluorescence spectrometer3 Method SummaryThe samples were prepared as borate glass melt samples. Samples measuring element and the effect of potassium is characterized by X-ray fluorescence spectrum Strength, calculated based on the calibration curve K (of K2O) content.4 ReagentsUnless otherwise indicated in the analysis using only recognized as analytical reagents. 4.1 lithium tetraborate and lithium metaborate mixed flux (67.33), X-ray fluorescence dedicated reagent. Before use at 650 ℃ burning 4h, then In the drier cooled storage. 4.2 bromide. 4.3 potassium chloride, high purity reagents or standard material. Burning 6h at 500 ℃, then cooled in a desiccator. 4.4 potassium, high purity reagents or standard material. Baking at 130 ℃ 2h, then cooled in a desiccator. 4.5 Sodium chloride, baked at 105 ℃ 2h, then cooled in a desiccator. 4.6 sodium sulfate, drying at 105 ℃ 2h, then cooled in a desiccator. 4.7 anhydrous calcium sulfate, at 500 ℃ burning 2h, cooled in a desiccator. 4.8 magnesia, calcined at 1000 ℃ 1h, then placed in a desiccator, weighed immediately after cooling. 4.9 saturated solution of lithium bromide. The lithium bromide (4.2) dissolved in water to saturation, and filtered. 4.10 mixture A. Take 7g sodium chloride (4.5), 2g of anhydrous calcium sulfate (4.7) and 1g of magnesium oxide (4.8), grinding mix, stored in a desiccator. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 3809-2014_English be delivered?Answer: Upon your order, we will start to translate SN/T 3809-2014_English as soon as possible, and keep you informed of the progress.
