Rapid multiresidue determination of bisphenol analogues in soil with on-line derivatization

摘要: Bisphenol analogues are compounds extensively used which have been potentially linked to adverse health effects. Nevertheless, few studies reported the analysis of compounds, other than bisphenol A, in environmental solid samples and none soil samples. In this study, a rapid sensitive analytical method is presented for simultaneous determination 13 bisphenols The combines ultrasonic-assisted extraction placed small columns GC-MS/MS analysis. Manual on-line derivatizations were compared results showed that significant higher chromatographic responses achieved with derivatization. Different parameters such as quantity derivatization agent, solvent, or time assayed. detection limits all target ranged from 0.04 0.27 ng g−1, BPC BPA, respectively. Analysis spiked gave satisfactory recovery results, 70 111%, compounds. Finally, validated was applied several Spanish areas, 3 (BPAF, BPF, BPA) detected, although only BPF BPA could be quantified levels up 127 ng g−1.
