Objectives To establish a purge and trap/gas chromatographic-mass spectrometric method for the determination of 10 kinds of volatile halogenated hydrocarbons, such as dibromoethane in water.
Methods The levels of volatile halogenated hydrocarbons in water samples were measured by MS in ISTD after being swept, captured and taken off, and separated by capillary column.
Results Good linear relations were observed in the range of 0.01~0.6μg/L for 10 kinds of volatile halogenated hydrocarbons, the correlation coefficient was greater than 0.999. The limits of detection were 0.008~0.02 μg/L, the recoveries were 95.3%~105.2%, the RSDs were 1.5%~4.6%.
Conclusions The method is fast, accurate, sensitive and suitable for the detection of 10 kinds of volatile halogenated hydrocarbons, such as dibromoethane in water.
