摘要
本文建立了锂离子电池生产排气中NMP(N-甲基吡咯烷酮)的溶液吸收法采样-浓缩-气相色谱测定、固相吸附管采样-溶剂解吸-气相色谱测定和固相吸附管采样-热脱附-气相色谱测定等3种方法,并应用于锂离子电池生产固定源排气、锂离子电池生产车间和周边环境空气现场监测,准确度均较好和精密度均较高,灵敏度依次提高。本文为锂离子电池生产固定源排气、锂离子电池生产车间和周边环境空气NMP测定提供了可供借鉴的成功案例,所采用的方法为准确监测锂离子电池生产企业NMP的排放特征、研究其环境影响,阐明NMP的空间分布与归趋,防治锂离子电池企业NMP乃至VOCs污染,提供了必要的研究基础和检测技术支持。
This paper established three methods for the determination of NMP(N-methylpyrrolidone)in the exhaust gas of lithium-ion battery production:solution absorption sampling concentration gas chromatography,solid-phase adsorption tube sampling solvent desorption gas chromatography,and solid-phase adsorption tube sampling thermal desorption gas chromatography.These methods were applied to the stationary source exhaust gas of lithium-ion battery production,on-site monitoring of the air in lithium-ion battery production workshops and surrounding environments,The accuracy and precision were both good,and the sensitivity increases sequentially.This paper provided successful cases for reference in the determination of NMP in the stationary source exhaust of lithium-ion battery production,lithium-ion battery production workshops,and surrounding environmental air.The methods provided necessary research foundations and detection technical support for accurately monitoring the emission characteristics of NMP in lithium-ion battery production enterprises,studying its environmental impact,elucidating the spatial distribution and fate of NMP,and preventing and controlling NMP and even VOCs pollution in lithium-ion battery enterprises.
