基于双配体有机骨架同时检测食品接触塑料中双酚A、双酚S的迁移量
Simultaneous Detection of Bisphenol A and Bisphenol S Migration in Food-Contact Plastics Based on a Dual-ligand Metal-organic Framework
摘要
Abstract
This study reported the synthesis of a novel composite material,Cu-BTC-HHTP/MWCNT.The material was synthesized via a solvothermal method using copper nitrate(Cu(NO3)2),1,3,5-benzenetricarboxylic acid(H3BTC),and 2,3,6,7,10,11-hexahydroxytriphenylene(HHTP)as dual-ligand metal-organic frameworks,which were incorporated into multi-walled carbon nanotubes(MWCNT)to create a composite with superior electrical conductivity.The material was characterized by scanning electron microscopy,X-ray diffraction,and Fourier transform infrared spectroscopy.A glassy carbon electrode(GCE)was modified with the Cu-BTC-HHTP/MWCNT composite to develop an electrochemical sensor,referred to as Cu-BTC-HHTP/MWCNT/GCE.Cyclic voltammetry was used to optimize the construction conditions of the sensor,including the choice of electrolyte,system pH,accumulation potential,and accumulation time.Under optimal conditions,the sensor exhibited a linear relationship between peak current response and bisphenol A(BPA)and bisphenol S(BPS)concentrations in the range of 5 to 400 μmol/L,with coefficient of determination(R2)of 0.997 for BPA and 0.998 for BPS.The detection limits were 76.4 nmol/L for BPA and 18.5 nmol/L for BPS.In real sample testing,the method demonstrated excellent recovery rates,ranging from 96.63%to 103.69%for BPA and from 98.29%to 101.18%for BPS.These results indicate that the Cu-BTC-HHTP/MWCNT/GCE sensor provides a robust platform for the detection of BPA and BPS migration from food-contact materials,providing a reliable analytical tool for investigating the migration of these contaminants.关键词
