Abstract

•Eco-friendly graphite rods exfoliation in Na2S2O3/(NH4)2SO4 mixture.•Few-layer graphene material with high sulphur doping degree.•Analytical utility of exfGR-S/GCE modified electrode in GA electrochemical assay.•Broad GA detection range (0.1–100.0 µM) with a low detection limit (3.03 × 10−8 M).•Practical applicability of exf-SGR/GCE sensor in green and black tea sample analysis.
