基于MWCNTs和Co-Fe双金属普鲁士蓝类似物的电化学传感检测牛奶中的H2O2
Electrochemical Sensor Based on MWCNTs and Co-Fe Bimetallic Prussian Blue Analogues for the Detection of H2O2 in Milk
摘要
Abstract
In this study,an enzyme-free electrochemical sensor(NF/Co-FePBA/MWCNTs/GCE)was developed by modifying a glassy carbon electrode(GCE)with Co-Fe bimetallic Prussian blue an-alog(Co-FePBA)and multi-walled carbon nanotubes(MWCNTs).The Co-FePBA acting as a hydro-gen peroxide-mimicking enzyme,electrocatalytically reduced H2 O2,generating a strong current re-sponse,for the rapid and sensitive electrochemical detection of H2O2 in milk.Under optimal condi-tions,the sensor demonstrated a broad linear range(0.01-5.0 mmol/L)and a low limit of detection(LOD=0.52 μmol/L,S/N=3)for the current response to H2 O2.Furthermore,the sensor exhibited strong anti-interference ability and good repeatability,reproducibility and stability.In milk sample detection,the sensor yielded recoveries ranging from 91.3%to 103%with relative standard deviation(RSD)≤2.7%(n=3).This electrochemical method enables a low-cost,simple,rapid and highly sensitive detection of H2O2 in milk.关键词
