A GC-MS method with headspace injection was established for the determination of styrene in sodium polystyrene sulfonate resin.Styrene-d8 was used as internal standard.A quartz capillary column was used by selective ion monitoring.The calibration curve of styrene was linear in the range of 0.5-1 5 μg/ml(r=0.999 5).The detection limit was 1 ng/g(1 ppb).
