Abstract

A rapid method for the detection of bisphenols was established by ultra performance convergence chromatography (UPC2). The migration rules of bisphenols in four different simulants including of pure water, acetic acid, ethanol and isooctane were first studied, and the effect of extraction solvent on recovery of bisphenols in aqueous simulants was also investigated. Furthermore, the influence of extraction solvent on recovery of bisphenols in aqueous simulants was discussed, and the relationship between migration amount of bisphenols and food simulants, migration time, migration temperature and other factors were explored. The experimental results showed that toluene exhibited the optimal extraction efficiency for bisphenols in aqueous simulants; bisphenols presented the most obvious migration in fatty food simulants; the migration amount of bisphenols increased with the extension of time; the migration rate and amount of bisphenols also enhanced with the increment of contact temperature.
