| Abstract: | An analytic method was developed for determination of triazine herbicides in water based on solid phase microextraction(SPME) and gas chromatography/mass spectrometry(GC/MS).The extraction ability of polydimethylsiloxane(PDMS)/divinylbenzene(DVB) and polyacrylate(PA) for triazine herbicides was compared,and PDMS/DVB was suitable for 11 selected triazine herbicides.To enhance the sensitivity of SPME,some important parameters such as pH,desorption temperature,extraction time and salt effect which affect on ad... |
