Foreword

This standard was drafted according to the rules given in GB/T 1.1-2009. This standard replaces SN/T 0860-2000 "Determination of Selenium in Export Mushrooms by Fluorescence Spectrophotometry." The main technical changes of this standard compared with SN/T 0860-2000 are as follows. --- The headline was changed to the determination method for selenium in export foods. The test sample was changed from export canned mushrooms to export food; --- Added the first method of inductively coupled plasma mass spectrometry; --- The original method of fluorescence spectrophotometry is not modified as a second method. This standard is proposed and managed by the National Certification and Accreditation Regulatory Commission. This standard was drafted by. Shanghai Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China. The main drafters of this standard. Shen Jinchao, Yang Zhenyu, Fan Xiang, Ni Tulu, Chen Zhangting, Song Qing, Li Wei, Zhang Hui. The previous versions of the standards replaced by this standard are. ---SN/T 0860-2000. Determination of Selenium in Exported Foods

1 Scope

This standard specifies the method of inductively coupled plasma mass spectrometry and fluorescence spectrophotometry for the determination of selenium in exported foods. The inductively coupled plasma mass spectrometry method of this standard is applicable to rice, biscuits, milk powder, milk-containing drinks, tea, grapes, peanuts and mushrooms Determination of selenium content in mushrooms and other samples. This standard fluorescence spectrophotometry method is suitable for the determination of selenium content in canned mushrooms.

3 Method summary

Selenium in the sample was digested by microwaves and dissolved in an acid solution. Selenium is ionized in the plasma and its characteristic mass is measured Counting, within a certain range, its count rate is proportional to the selenium content. Standard curve internal standard method.

4 Reagents and materials

The test water meets the requirements for secondary water in GB/T 6682. 4.1 65% Nitric Acid. Excellent Grade. 4.2 2% nitric acid. Take 2mL of nitric acid (4.1) and dilute to 100mL with water. 4.3 Isopropyl alcohol. chromatographic purity. 4.4 Selenium standard solution. 1g/L, certified reference material, medium 5% nitric acid. 4.5 Selenium Standard Stock Solution. Diluted selenium standard solution (4.4) to 10mg/L in proportion, and the final medium was nitric acid (4.2). The solution is normal It is valid within 15 days under warm sealed storage conditions. 4.6 Selenium standard curve solution. Diluted selenium standard solution (4.5) in proportion to 5 levels. 0.5μg/L, 1μg/L, 2μg/L, 5μg/L, At 10 μg/L, the final medium was nitric acid (4.2). The solution was effective within 15 days at room temperature in a closed storage condition. 4.7 锗 standard solution. 1g/L, certified reference material. 4.8 internal standard solution. according to the proportion of standard solution (4.7) diluted to 50μg/L, the final medium is nitric acid (4.2), and add isopropyl alcohol (4.3), Mix well so that the final concentration of isopropanol is 0.5% (v/v). The solution is ready for use.
