Appendix A

Testing method A.1 General Provisions Unless otherwise specified in this standard, it should be of analytical grade purity of the reagents, the titration standard solution, the determination of impurities with a standard solution, the formulation And products shall GB/T 601, GB/T 602, a predetermined preparation GB/T 603, the test water shall meet the GB/T 6682 in three water gauge set. The test does not indicate when the solution which is formulated with a solvent, refer to the aqueous solution. A.2 mass percent of total organic selenium Selenium A.2.1 Reagents and solutions A.2.1.1 nitric acid. pure class. A.2.1.2 perchloric acid. pure class distinctions. A.2.1.3 hydrochloride. excellent pure. A.2.1.4 Sodium hydroxide. pure class. A.2.1.5 mixed acid. nitric acid, perchloric acid (41). Hydrochloric acid solution A.2.1.6. 6mol/L. Sodium borohydride solution A.2.1.7. 8g/L. Weigh 8.0g of sodium borohydride (of NaBH4), was dissolved in sodium hydroxide solution (5g/L), the volume to 1000mL. A.2.1.8 potassium ferricyanide solution. 100g/L. Weigh 10.0g of potassium ferricyanide [K3Fe (CN) 6], the volume with the amount of distilled water to dissolve 100mL, and mix. Standard stock solution A.2.1.9 Se. Se accurately weighed 100.0mg (spectroscopically pure), was dissolved in a small amount of nitric acid, perchloric acid was added 2mL, boiling water bath Heated 3h ~ 4h, cooled plus 8.4mL of hydrochloric acid, and then cooked in boiling water bath for 2min, dilute to 1000mL, this concentration of stock Equivalent to 100μg per ml selenium. A.2.1.10 selenium standard test solution. Take 100μg/mL standard stock solution of selenium 1.0mL, water volume to 100mL, concentration of this experiment 1μg/mL. A.2.2 Instruments and Equipment A.2.2.1 AFS-230 dual channel atomic fluorescence spectrometer or similar instrument. A.2.2.2 electric hot plate. A.2.2.3 automatic temperature control digestion furnace. Preparation of inorganic selenium measurement sample A.2.3 Weigh about 1g sample accurately to 0.0001g, in 50mL beaker was added 25mL of water, stirred on a magnetic stirrer 30min, The sample was fully dissolved, transferred to a 100mL volumetric flask, add water, shake, stand in a refrigerator (4 ℃) 1h. The solution volume in the 5000r/min centrifugal 30min, while the blank test. The supernatant in 10mL 50mL volumetric flask, were added 12.5mL Hydrochloric acid, 2.5 mL of potassium ferricyanide solution, constant volume, mix tested. A.2.4 Analysis step Determination of Inorganic selenium content in accordance with GB 5009.93 atomic fluorescence spectrometry, total selenium content and then subtracted from the previously obtained containing inorganic selenium An amount to give the content of organic selenium, to calculate the percentage of organic selenium. A.2.5 calculation results A.2.5.1 inorganic selenium content X1, in milligrams per kilogram (mg/kg), calculated according to formula (A.1). X1 = (C2-c1) × 100 × 1000 m1 × 1000 × 1000 (A.1) Where. C2 --- sample extract concentration measured in units of nanograms per milliliter (ng/mL); C1 --- blank measurement of inorganic selenium concentration, in units of nanograms per milliliter (ng/mL); 100 --- constant volume of the sample in milliliters (mL); 1000 --- conversion factor; M1 --- mass of the sample taken when said inorganic selenium measured in grams (g). Results retention three significant figures. A.2.5.2 content of organic selenium X2, in milligrams per kilogram (mg/kg), calculated according to formula (A.2). X2 = X-X1 (A.2) Where. X---- total content of selenium in the sample, in milligrams per kilogram (mg/kg); The content of the X1 --- inorganic selenium in the sample, in milligrams per kilogram (mg/kg). Of the total selenium content of organic selenium A.2.5.3 mass fraction w1, according to equation (A.3) is calculated. w1 = X2 X × 100% (A.3) Where. An X2 --- selenium content of the organic sample, in milligrams per kilogram (mg/kg); X---- total content of selenium in the sample, in milligrams per kilogram (mg/kg). The test result to the arithmetic mean of replicates results. Results reserved to a decimal point.
