Background:
Bisphenols are major industrial chemicals that have raised public concern due to their endocrine
disrupting properties and toxicity. Sample preparation is the most critical step for determination of bisphenols, especially
if the analyst has to deal with environmental samples which are complex matrices and the co-extraction and co-elution of
other relevant compounds results in the enhancement or suppression of the analyte signal. The need for the precise
determination of bisphenols has signaled the development of effective microextraction techniques according to the Green
Analytical Chemistry (GRAC) guidelines.
Objective:
The objective of this review is to gather and discuss all the recent advances in the development of
microextraction techniques such as solid phase extraction (SPE), solid phase microextraction (SPME), magnetic solid
phase microextraction (MSPE), liquid-phase microextraction (LPME), dispersive liquid-liquid microextraction (DLLME),
stir bar sorptive extraction (SBSE), matrix solid-phase dispersion (MSPD), that have been successfully applied in the
extraction of bisphenols from environmental matrices.
Conclusion:
The analytical performance of the proposed techniques is critically discussed highlighting the potential and
the limitations of each method.
