摘  要:
分别采用液相色谱法和气相色谱法测定了吡虫啉生产废水中咪唑烷、丙烯腈和N,N-二甲基甲酰胺的含量。采用HypersilODS2色谱柱,流动相为甲醇-水(体积比2∶8)测定废水中咪唑烷;丙烯腈和N,N-二甲基甲酰胺的测定条件为PEG-20M毛细管,FID检测器,汽化温度分别为165、200℃,柱温分别为60、120℃。实验测得吡虫啉生产废水中含有咪唑烷0.31%、丙烯腈0.38%、N,N-二甲基甲酰胺0.29%。

摘  要:
The content of 2-(nitroimino)imadazolidine, acrylonitrile and N,N-dimethylformamide was conducted in the production of wastewater of imidacloprid by HPLC and GC. The liquid chromatography was carried out by Hypersil-ODS2. Determined 2-(nitroimino)imadazolidine with mobile phase of methanol and water(2:8, by vol). The GC was carried out by PEG-20M capillary, FID detector for determining acrylonitrile and N,N-dimethylformamide. The vaporization temperature were 165, 200 °C and column temperature were 60, 120 °C. The content of 2- (nitroimino)imadazolidine, acrylonitrile and N,N-dimethylformamide are 0.31, 0.38, 0.29%.
