光电化学除草剂检测系统设计

Electrode preparation for photoelectrochemical herbicide detection

我国农作物生产中化学除草剂被广泛使用,但除草剂的残留会威胁人们的生命健康。基于纳米技术和光电化学技术,研制的Au/ZnO/Co_(3)O_(4)/NF纳米复合材料除草剂残留传感器具有灵敏度高、检测限低等特点,以Au/ZnO/Co_(3)O_(4)/NF纳米复合材料除草剂残留传感器电极为基础,结合嵌入式技术设计的传感器样机成本低、制作工艺简便、操作简单,为新型光电化学除草剂残留传感器的研制提供了很好的研究案例,有一定的科研和应用价值,特别是在农业领域具有较大的应用前景。

At present,chemical herbicides are widely used in crop production in China,but the residue of herbicides will threaten people's lives and health.Based on nanotechnology and photoelectrochemical technology,the Au/ZnO/Co_(3)O_(4)/NF nanocomposite herbicide residue sensor developed in this paper has the characteristics of high sensitivity and low detection limit,based on the Au/ZnO/Co_(3)O_(4)/NF nanocomposite herbicide residue sensor electrode designed with embedded technology,the sensor prototype designed with low cost,simple production process and simple operation provides a good research case for the development of new photoelectrochemical herbicide residue sensor.It has certain scientific research and application value,especially in the field of agriculture.
