摘要： A three-dimensional Cu2O/electrochemically reduced graphene (ErGO)-modified electrode was developed for the determination of dimetridazole. Cu2O/GO was initially prepared using a modified solvothermal method, and the 3D structure was constructed by electrodepositing a Cu2O/GO dispersion on a glassy carbon electrode in the presence of lithium perchlorate. The enhanced electrocatalytic reduction of dimetridazole was confirmed, and the electrochemical reduction reaction was found to be a typical adsorption-controlled process. Our results revealed that the response to dimetridazole was linear in the concentration range of 30-150 nmol L-1 and the detection limit was 3.64 nmol L-1. The prepared electrode was also employed to detect dimetridazole in an egg sample, thereby indicating its potential practical application.
