FeZr-MOF纳米酶的制备及其用于双酚S的比色传感检测
Synthesis of FeZr-MOF nanozymes and their application in colorimetric sensing detection of bisphenol S
制备了具有过氧化物酶活性的FeZr-MOF并构建了用于双酚S检测的比色传感器,实现了对双酚S的检测。FeZr-MOF纳米酶具有类过氧化物酶活性,可以催化TMB-H2O2氧化还原反应,使溶液颜色变蓝。进一步研究发现,双酚S可以抑制FeZr-MOF的活性,抑制反应体系的显色反应,使得溶液颜色变浅,可以通过观察溶液的颜色变化来达到检测双酚S的目的。在最优实验条件下,对双酚S进行定量分析,比色传感器的线性范围为20~2 000 μmol/L,检测限为7.29 nmol/L。该检测方法不需要使用昂贵的分析仪器,通过肉眼直接观察即可实现对双酚S的检测,检测步骤简单,检测时间短。
FeZr-MOF with peroxidase-like activity is prepared,and used to establish a colorimetric sensor for the detection of bisphenol S.This FeZr-MOF nanozyme exhibits peroxidase-like activity,enabling it to catalyze TMB-H2O2 redox reaction and turn the solution blue.Further studies reveal that bisphenol S can inhibit the activity of FeZr-MOF and the chromogenic reaction of the system,causing the solution to become lighter in color.The detection of bisphenol S can be achieved through observing these color changes in solution.Under the optimal experimental conditions,the colorimetric sensor is used for quantitative analysis of bisphenol S,showing a linear range of 20-2 000 μmol/L and a detection limit of 7.29 nmol/L.This detection method does not require expensive,large analytical instruments,and can be performed by simply observing the solution’s color changes with the naked eye.The procedures are simple,time-efficient,and easy to implement.
