Determination of potassium oxide content1 ScopeThis part of GB/T 6609 specifies the method for determining the content of potassium oxide in alumina. This section applies to the determination of potassium oxide content in alumina. Method 1 Determination range. 0.002%~0.12%; Method 2 Determination range. 0.002%~0.20%. 2 Method 1. Flame photometry 2.1 Principle of the method After the sample is sintered at a high temperature with boric acid and starch, potassium is converted into borate, and after leaching with water, the insoluble matter is separated. Add n-butanol for sensitization For the determination of potassium oxide content by flame photometry. 2.2 Reagents and materials Unless otherwise stated, only reagents and secondary waters identified as superior grades were used in the analysis. 2.2.1 Boric acid. 2.2.2 Potassium chloride. The reference potassium chloride is placed in platinum rhodium (2.3.1), fired at 500 ° C for 2 h, placed in a desiccator (2.3.4), and cooled to Room temperature. 2.2.3 Sodium chloride. The reference sodium chloride is placed in platinum rhodium (2.3.1), fired at 500 ° C for 2 h, placed in a desiccator (2.3.4), and cooled to Room temperature. 2.2.4 Starch. If the blank value is high, it is repeatedly washed and purified by water with a pouring method, then washed twice with absolute ethanol to dry, and then finely ground for use. 2.2.5 Hydrochloric acid (1 19). 2.2.6 Boric acid solution (29g/L). 2.2.7 n-butanol. 500mL n-butanol was placed in a 1000mL separatory funnel, 150mL water was added, shaken for 3min, layered, discarded Go to the water phase. It was extracted twice with water (about 75 mL each time). 2.2.8 Potassium oxide standard storage solution. Weigh 0.1583g of potassium chloride (2.2.2) dissolved in water, transferred to 1000mL volumetric flask, diluted with water Release to the scale, mix and store in a polyethylene bottle. 1 mL of this solution contained 0.1 mg of potassium oxide. 2.2.9 Sodium oxide standard storage solution. Weigh 1.8859g sodium chloride (2.2.3) dissolved in water, transferred to 1000mL volumetric flask, diluted with water Release to the scale, mix and store in a polyethylene bottle. 1 mL of this solution contained 1 mg of sodium oxide. 2.2.10 Potassium Oxide Standard Solution. Pipette 25.00 mL of potassium oxide standard stock solution (2.2.8) into a 100 mL volumetric flask. Press again Add the ratio of sodium oxide to potassium oxide in the sample, add the standard storage solution of sodium oxide (2.2.9), dilute to the mark with water, and mix. This solution 1 mL contains 0.025 mg of potassium oxide. Available when used. 2.2.11 Working curve solution. In a set of 100mL volumetric flask, add potassium oxide standard solution (2.2.10) according to Table 1, add 30mL boron Acid solution (2.2.6), 7mL n-butanol (2.2.7), add water to about 95mL, shake, so that n-butanol is completely miscible, diluted with water to the mark, Mix well. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 6609.6-2018_English be delivered?Answer: Upon your order, we will start to translate GB/T 6609.6-2018_English as soon as possible, and keep you informed of the progress.
