This section was drafted in accordance with the rules of GB/T 1.1-2009. This part is proposed and managed by the National Certification and Accreditation Regulatory Commission. This section was drafted by. Guangxi Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China and Jiangxi Entry-Exit Inspection Inspection Epidemic Bureau. The main drafters of this section. Shang Jie, Yan Chun, Liu Xiuhong, Zou Yanhua, Xiao Huanxin. Fireworks, fireworks, pyrotechnics Part 20. Determination of antimony content Flame Atomic Absorption Warning. The personnel using this section should have practical experience in regular laboratory work. This section does not indicate all possible security issues. It is the user's responsibility to adopt appropriate safety and health measures and to ensure compliance with the conditions set by the relevant national laws. This section deals with fireworks Pharmacy is a flammable and explosive dangerous goods. The following are the most important safety technical regulations. a) The preparation of the sample should be carried out under conditions with safety precautions; b) The preparation and storage of the sample shall not exceed the conditions allowed by the safety protection; c) The sample should be dried in a safe explosion-proof drying oven. Its drying temperature should not exceed 55°C.

1 Scope

This part of SN/T 1732 specifies flame atomic absorption spectrometry for the determination of antimony in pyrotechnic compositions for fireworks and firecrackers. This section applies to flame atomic absorption spectrometry for the determination of pyrotechnic compositions of fireworks. Measurement range. yttrium content (with yttrium mass Score) is greater than 0.5%.

2 Normative references

3 Principle

After appropriate pretreatment of the sample, it was filtered to constant volume. The sample solution is injected into the flammable air-acetylene flame to form a helium ground state in a high-temperature flame. The 553.6nm characteristic line emitted by the sub-half hollow cathode lamp selectively absorbs, and its absorbance value is proportional to the mass concentration of helium.

4 Reagents

Unless otherwise stated, only analytically pure reagents and at least Grade 3 water specified in GB/T 6682 were used in the analysis. 4.1 Ethanol. 4.2 Acetone. 4.3 nitric acid, superior grade pure. 4.4 Nitric acid solution (15). 4.5 Nitric acid solution (1 99). 4.6 Acetic acid. 4.7 Barium nitrate, spectrally pure. ......
