Abstract

This study intends to investigate the utilization of graphene-based electrochemical sensors for detecting pesticide residues. By means of literature investigation and experimental examination, the working principle, performance and practical application of graphene electrochemical sensors are comprehensively researched. We find out that due to its special electric and chemical characteristics, graphene can sense pesticide residues with high sensitivity and selectivity. The sensor can quickly and accurately detect the pesticides in the sample, and it also shows great promise for simultaneously detecting multiple types of pesticides. Actual sample testing has shown some initial results. Graphene based electrochemical sensors have a wide range of applications in the field of pesticide residue detection, and they are expected to become an alternative to traditional detection methods, which will provide strong support for food safety and environmental protection.
