Design of sulfonic group based hyper cross-linked polymer as adsorbent for efficient enrichment of endocrine...

The necessity for the development of effective adsorbents to capture endocrine disrupting chemicals (EDCs) from environmental and food samples arises from the potential health hazards that the EDCs may impose on human beings. Hence, a novel sulfonic group based hyper cross-linked polymer (HQSA-PLE-HCP) was synthesized and explored in solid phase extraction for the enrichment of some EDCs. The HQSA-PLE-HCP demonstrated an excellent adsorption capability for some EDCs (bisphenol F, bisphenol A, bishydroxyphenylbutane and p-tert-butylphenol). The newly developed SPE with HQSA-PLE-HCP as the adsorbent coupled with high-performance liquid chromatography-ultraviolet detection showed a good linear dynamic response range (0.13-400 ng mL^-1 (ng g^-1), r² ≥ 0.9988) and satisfactory method recoveries (83.0%-119 %, RSD ≤9.9 %) for the determination of the EDCs in bottled water, green tea drink and honey samples. The limits of detections for the analytes were in the range of 0.04-2.50 ng mL^-1 (ng g^-1), and the limit of quantifications were in the range of 0.13-8.33 ng mL^-1 (ng g^-1), depending on both the compounds and sample matrix. This study offers an alternative approach of an effective method for the quantification of some EDCs in some food samples.
