Abstract

Bisphenols (BPs) are typical endocrine disruptors, which can cause great effects on environmental, organisms and human health. In this study, β-Cyclodextrin (β-CD) functionalized polyamidoamine dendrimers-modified Fe₃O₄ nanomaterials (MNPs@PAMAM (G3.0)@β-CD) were facilely synthesized. It exhibited good adsorption capacities for BPs, which was utilized to construct a sensitive tool in combination with high performance liquid chromatography for monitoring BPs such as bisphenol A (BPA), tetrabromobisphenol A (TBBPA), bisphenol S (BPS), bisphenol AF (BPAF) and bisphenol AP (BPAP) in beverage samples. The factors affecting the enrichment were examined such as generation of adsorbent, dosage of adsorbent, type and volume of eluting solvent, elution time and pH value of sample solution. The optimal parameters for enrichment was as follows: dosage of adsorbent, 60 mg; adsorption time, 50min; sample pH, pH7; elutent, 9 mL mixture of methanol and acetone(1:1); elution time, 6min; sample volume, 60 mL. The experimental results demonstrated that the adsorption conformed to pseudo-second-order kinetic model and Langmuir adsorption isotherm model. The results showed the maximum adsorption capacities of BPS, TBBPA, BPA, BPAF and BPAP were 131.80 μgg^-1, 139.84 μgg^-1, 157.08 μgg^-1, 142.11 μgg^-1 and 134.23 μgg^-1, respectively. Under optimal conditions, BPS had good linear relationship over range from of 0.5-300 μgL^-1, and the linear ranges of BPA, TBBPA, BPAF and BPAP ranged from 0.1 to 300 μgL^-1. The limits of detection (S/N = 3) for BPs were good in range of 0.016-0.039 μgL^-1. The spiked recoveries of target bisphenols (BPs) in beverages were approving over range from 92.3% to 99.2%. The established method possessed merits of easy to operate, good sensitivity, rapidness as well as environmental friendliness, and which earned great application potential for the enrichment and detection of trace BPs in practical samples.
