Abstract

Taking Zn-Fe bimetallic organic-framework as both template and precursor, and furfuryl alcohol (FA) as secondary carbon source, a high-surface-area magnetic nanoporous carbon (MNPC) material was successful prepared. The MNPC exhibits excellent adsorption performance for bisphenol analogs (BPs). The maximum adsorption capacity achieved 439.0 mg g^-1 for bisphenol AF, 423.7 mg g^-1 for bisphenol S, 330.4 mg g^-1 for tetrabromobisphenol A and 252.5 mg g^-1 for bisphenol A. A sensitive magnetic solid-phase extraction with MNPC as adsorbent coupled with HPLC-UV analytical method was developed for the detection of trace BPs. The limits of detection for BPs were as low as 0.03-0.07 ng mg^-1 with the RSDs of less than 4.6%. This method was applied to detection of four BPs in environmental water samples and the satisfactory results were obtained.
