This paper presents a greener methodology for the first time to determine streptomycin in honey based on the modification of gel in the gel electromembrane extraction (G-EME) technique using exfoliated graphene (EG). Differential pulse voltammetry (DPV) with a modified screen-printed carbon electrode was used as a detection technique. The EG was prepared by applying an electrochemical exfoliation of pencil graphite as an environmentally friendly and simple method.
