本文通过水热合成法合成一种金属-有机骨架材料(MOFs)——MIL-101,将其修饰在玻碳电极上制得电化学传感器(MIL-101/GCE)用于吗啡的快速灵敏检测。吗啡在MIL-101/GCE上的电化学行为用差分脉冲伏安法、循环伏安法来表征。在最佳条件下,测定吗啡的线性范围为1.5×10~(-6)~2.0×10~(-4)M,检测下限为5×10~(-7)M,相关系数为0.9911。将该传感器用于血清中吗啡的检测,回收率为101.7%,结果令人满意。说明该传感器有良好应用前景。
In this paper, a kind of metal-organic framework material (MOFs) -MIL-101 was synthesized by hydrothermal method, which was modified on glassy carbon electrode to prepare electrochemical sensor (MIL-101 / GCE) for rapid and sensitive detection of morphine . The electrochemical behavior of morphine on MIL-101 / GCE was characterized by differential pulse voltammetry and cyclic voltammetry. Under the optimal conditions, the linear range of determination of morphine was 1.5 × 10 -6 -6.0 × 10 -4 M, the detection limit was 5 × 10 -7 M, and the correlation coefficient was 0.9911. The sensor for the detection of morphine in serum, recovery was 101.7%, the results are satisfactory. Indicating that the sensor has a good prospect.
