    Dispersive micro-solid phase extraction of bisphenol A from

    In this paper, an estrogenic endocrine-disrupting monomer, bisphenol A, is determined in different kind of milk samples (whole, defatted, and skim). The extraction procedure is carried out using a magnetic-nylon 6 composite in a dispersive micro-solid phase extraction format, the analyte being finally determined by HPLC-UV.

    Dispersive micro-solid phase extraction of bisphenol A from

    Herein, a new method for the determination of bisphenol A (BPA) in milk samples is presented. This method comprises a precipitation process, bearing in mind that the analyte has a high tendency to interact with the fatty compounds of the milk, and a magnetic micro-solid phase extraction prior to the determination by high-performance liquid chromatography with UV detection.
