Analysis of N-methylpyrrolidinone in aramid fiber by gas chromatography/mass spectrometry method
摘要
Abstract
N-methylpyrrolidinone (NMP) was commonly used as reaction solvents in the synthesis of ara-mid fiber. A gas chromatography/mass spectrometry (GC/MS) method of determination of N-methylpyrrolidi-none in textiles was established by improving the extraction method and GC/MS conditions. The samples were extracted with ethyl acetate by ultrasound assisted procedure.After being concentrated and purified with filter paper, the extract was quantitatively determined using GC/MS by external standard method and positive-ly confirmed through selected-ion monitoring mode. The results showed that while the dosage of N-methyl-pyrrolidinone was 1~10 μg/mL, the method provided 95.8% of recovery rate, lower than 5% of relative stan-dard deviations and 0.05 μg/mL of determination limit. The method was simple, and had high sensitivity and good repeatability, which could be used in the residual content determination of NMP in aramid fiber.关键词
