摘要：

A method for the determination of volatile compounds present in aqueous solutions is presented, based on microextraction by demixing with 2-propanol. The extraction properties of various solvents were examined and the method was optimized. The method is rapid and precise and enables detection limits of 1-mu-g l-1 to be attained with flame ionization detection using only one concentration step.
