Solid phase extraction and spectrofluorometric determination of leached bisphenol A from some polycarbonate products under simulated use conditions using surface molecularly imprinted magnetite nanospheres

Abstract

This work reports on synthesis of a novel magnetic nanoadsorbent for solid phase extraction of leached bisphenol A (BPA) from some polycarbonate products. In order to improve the adsorbent selectivity toward the analyte, the adsorbent was coated with a layer of BPA imprinted polymer. The prepared 10 adsorbent has been fully characterized using Fourier transform infrared spectrometer, X-ray diffractometer and transmission electron microscope. The results showed that, after carful optimization of various affecting factors on the removal and desorption of BPA, the analyte can be determined in the concentration range of 5.0-1000.0 ng mL -1 with a detection limit as low as 1.5 ng mL -1 using the spectrofluometric method. The results of the real samples analysis showed that the investigated samples 15 release detectable and considerable amounts of BPA into the water under simulated use condition confirming the previous concerns about danger of polycarbonate products usage in daily human life.

Molecularly imprinted polymers for the analysis and removal of polychlorinated aromatic compounds in the environment: a review

“…125 During thermal processes, BPA can leach from polycarbonate plastics, epoxy resin products, and PVC pipes into water where concentrations between 4.0-1730 µg L −1 in water from PVC tubes, and 0.05-2.47 µg g −1 in plastic products exposed for a maximum of 24 h have been reported. 126,127 Once in water, BPA can easily react with residual chlorine to form chlorinated BPA congeners, thus demanding for monitoring chlorinated derivatives for minimizing potential human exposure.…”

Rapid Extraction of Bisphenol A by Dispersive Liquid-liquid Microextraction based on Solidification of Floating Organic

“…Determination of BPA in food and beverages has been frequently reported due to the leaching of BPA from the polycarbonate and epoxy resin based-packaging containers, especially when the containers are aging, repeatedly used or subjected to heat (Bae et al 2002;Cooper et al 2011;Kubwabo et al 2009;Le et al 2008). Determination of BPA residues with SPE was frequently reported (Cao et al 2009;Gallart-Ayala et al 2011;Grumetto et al 2008;Madrakian et al 2015;Maragou et al 2006) mainly because the SPE is simple, sensitive and able to process multi samples at one time. The modification of SPE and LLE into the microextraction formats have greatly reduced the organic solvent used in the analysis.…”

Elaboration of an Imprinted Polymer Film Based on Chitosan Electrodeposition for the Voltammetric Detection of BPA

“…1 Thus, a reliable method to detect this endocrine disruptor is needed. Several techniques have been reported for the detection of BPA such as capillary electrophoresis, 4 high performance liquid chromatography (HPLC), 5 spectrofluorimetry, 6 gas chromatography tandem mass spectrometry, 7 enzyme linked immunosorbent assay (ELISA), 8 flow injection chemiluminescence. 9 These techniques have limitations such as expensive instruments, time consuming, complicated procedures and sample pre-processing steps.…”
