英文摘要: Phthalic acid ester is a kind of common environmental pollutants. Here, a method for fast screening trace phthalic acid ester in wine was constructed based on ion mobility spectrometry (IMS). Tube temperature and inlet temperature were optimized, and five typical phthalic acid esters were detected successively. Under the optimal tube temperature of 90 degrees C and inlet temperature of 160 degrees C, the limits of detection for dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), diisobutyl phthalate (DIBP) and diethylhexyl phthalate (DEHP) are 0.14, 0.06, 0.14, 0.44 and 0.02 mg/L, respectively, and the relative standard deviation (RSD) of 9 times measurements are less than 8.9%. The analytical time for single sample is less than 95 s. At last, five types of white wines were analyzed and the suspicious problem samples were successfully screened. And a home. made ion trap mass spectrometer was used to verify the product ions of phthalic acid ester detected by IMS and the interferences in wines can be avoided with acetone as dopant. The results demonstrate that the IMS can be used for rapid screening of trace phthalate esters in wine.
