摘要: 采用单宁酸对铜金属有机骨架材料蚀刻的策略,制备得到一种疏松多孔的CuO(记为E-CuO),并将E-CuO修饰在玻碳电极上(E-CuO/GCE)用于葡萄糖的电化学传感研究。结果表明:在0.25~2 000 μmol·L-1葡萄糖浓度范围内,E-CuO/GCE具有0.273 μA·μL·mol-1·cm-2的较高灵敏度及良好的抗干扰性能、重现性和稳定性。在实际样品分析中,E-CuO/GCE在蜂蜜和水果糖的加标回收率实验中表现良好,可用于葡萄糖注射液中葡萄糖的直接测定。 |

Abstract: Based on an etching strategy of treating a Cu-organic framework with tannic acid, a loose and porous CuO (denoted as E-CuO) was obtained. E-CuO modified glassy carbon electrode (E-CuO/GCE) was applied in the electrochemical sensing of glucose. E-CuO/GCE showed a high sensitivity of 0.273 μA·μL·mol-1·cm-2 in the glucose concentration range of 0.25-2 000 μmol·L-1, as well as good anti-interference performance, repeatability and stability. In the analysis of practical samples, E-CuO/GCE performed well in the experiment of spiked recoveries of honey and fruit sugar, and E-CuO/GCE could be used in glucose detection in glucose injection. |
