摘　　要：以四氧化二氮为原料,经预脱水、深度脱水和精馏等处理工艺制备了7种浓度的四氧化二氮微量水标准物质。其中自行研制的GM-04吸附剂,很好地解决了制备标准物质所需的四氧化二氮原料中微量水脱除的技术关键。经F检验法表明该标准物质均匀性良好,经过16个月的稳定性检验表明,该标准物质稳定性良好。与国内同类产品相比,所研制的标准物质浓度梯度范围设置更广,可实现对四氧化二氮和绿氮产品进行质量控制和提供准确可靠测试数据的目的。Seven reference materials of different concentrations of nitrogen tetroxide minim water were prepared by pre-dehydration, deep-dehydration, rectification, etc. treatment technics with nitrogen tetroxide as the raw material. The main technical problem of removing the minim water from mtrogen tetroxide was commendably settled by self-made GM-04 sorbent. The homogeneity of the reference materials by F examination method was well. The stability examination for 16 months shows that the stability was well too. The reference materials have wider-range concentration grads compared with the domestic similar products, the materials can be used to achieve quality control of nitrogen tetroxide and green nitrogen product, and provide exact determination datas.
