Determination of Trace Trifluoroacetic Acid in Surface Waterby Gas Chromatography-Mass Sepctrometry

Zhang Jianbo * , Hu Jianxin,Zeng Zheng, Zhu Yan(Department of Environmental Sciences, College of Environmental Sciences, Peking University, Beijing 100871)  
A set of analytical method for determining trace trifluoroacetic acid (TFA) in surface water is described , which includes the pre-treatment, preserving, concentrating and determining of the samples. The headspace auto sampler was elected to form the entire analytical instrument systems integrating with gas chromatography (GC) and mass spectrometry (MS). The TFA was changed into mehtyl-trifluoroacetate (MTFA) with dimethyl sulfate (DMS) at 80℃. Then the concentration of TFA in water samples was obtained by determining the concentration of MTFA with headspace sampling and GC-MS, using the volatility of MTFA. The limit of detection of the analytical method was 3 μg/L for TFA, the recovery of TFA ranged from 84% to 92%. The concentration of TFA in some surface water samples of Beijing were determined by applying the analytical method. The results indicate that the concentrations of TFA range from 43 to 107 ng/L in surface water in Beijing.
