The standard for the quality of wood products in Inner Mongolia is to resist the flow of Mi Huike before, and the Ministry of Foreign Affairs is still in the wild licorice Rencheng two-grade licorice. When formulating this part, we must take into account the regional differences and your overall habits, and retain the standards of Xi Erzhuo and 1, but the white Ding’s appearance classification is inconsistent, and the internal quality certification index is similar, so it is still classified into one standard, only the technical people’s evil requirements are different, and this part is proposed by the State Administration of Traditional Chinese Medicine. The starting unit of the part is: Send Western Chinese Medicine Research New, Inner Mongolia accounts for Yikepan with medicine division company, Xia Lingshi medical village company. Regular staff of this part: Gai Lan, Chang Siwei, Xu Yonghu, Xian Xueli, She Wenjie, Kuanmin, Li Yongkuan. 1Fan Chen

The total volume of the solution is 100%, and the solution is purified by the 6.4.4.3.1.2 purification method. The sulphuric acid layer should be purified according to the steps in the previous step, and the sulphuric acid layer should be washed with a colorless 2% sodium pyrolysis water solution to remove all the mercaptoaldehyde. Wash it for 1 time, each time with 2% 1. Vibrate the mixture and let it stand for 3 times. The lower layer is filtered out with water. The extract is filtered out with 1% anhydrous sulfuric acid, and then added to the funnel containing 3% sodium pyrosulfate and washed with 1% sodium pyrosulfate solution. Place it under water bath and burn it. ml is the final sample after the above treatment. When the sample is tested, 1 ml can be obtained.

Place it in a flask and add 10.5% MgSO4 in ethanol to make the sample completely decompose. Heat it at 80°C and bake it at 60°C. Heat it on a hot plate (careful to avoid burning) to make it completely carbonized. Place it in a high temperature furnace at H00 Heat to 45 for 2 hours, 4. Collect and cool to room temperature. Add 2% nitric acid to dissolve, and then steam on a hot plate (note that it is not completely dissolved), and then transfer to a high temperature shovel for decomposition. If it is still not completely decomposed, add 20% nitric acid to decompose it. After three times of decomposition, cool to room temperature. Add 5 ml. Heat on a hot plate at low temperature (1) to complete the decomposition. Transfer to a volumetric flask for washing 3 times, wash the liquid with high temperature water until the liquid is decomposed, and take the supernatant for graphite analysis. When the liquid is still decomposed, there is no precipitate of basic acid in the melt, which does not affect the analysis). 6.1.5.3.2 Preparation of blank solution Without adding sample, prepare blank solution according to the method of “Preparation of test solution” in 6.4..3.1. 6.4.5.3.3 Under the conditions of the test instrument, add two pipette cups with 1 L of standard lead solution, test solution and blank solution respectively, and inject them into the test tubes. Determine the absorbance of each solution by spectrophotometry. Draw a standard curve with the standard lead concentration/m corresponding to its absorbance according to GB/T 19618-7024, and calculate the lead concentration from the standard curve based on the double optical change of the test solution and the blank solution.
