摘要：

A mathematical model was developed for aqueous sample analysis by membrane extraction with a sorbent interface (MESI). The model used in this paper includes the consideration of boundary layers which are located inside and outside of the membrane, In this study, benzene, toluene, ethylbenzene, trichloroethylene and hexane were the standard test analytes, Distribution constants of these analytes between the membrane and water mere measured, Some significant parameters were investigated, such as agitation, temperature and headspace effect, Good agreement was found between the model and the experimental results.
