A simple method is set up by high performance liquid chromatography (HPLC) with UV-detector for determination of methyl ethyl ketone, α-Butanone, 2-Pyrrolidone and N-Methyl pyrrolidone in light industrial prod-ucts. 0.1% sodium dodecyl sulfonate aqueous solution is used for the ultrasonic extraction at 40 ℃. Under optimal conditions, the quantification limits for the desired compounds ranging from 20 μg/L to 40 μg/L were obtained, and the recoveries were higher than 91.6%. The proposed method was successfully applied to the determination of the target compounds in light industrial products with a higher sensitivity and simpler extraction than traditional gas chromatography methods.
