• AgNPs were successfully anchored onto MWCNTS via metal-carbon interface forming MWCNTs-Ag nanocomposite with enhanced electrocatalytic properties. • Sensitive, stable, reproducible and repeatable simultaneous stripping detection of Cu 2+ , Cd 2+ and Pb 2+ metal ions was achieved. • GCE/MWCNTs-Ag exhibited ultra-trace detection limits below the WHO drinking water limits • Competitive adsorption and co-deposition during simultaneous stripping detection revealed dynamic interfacial interactions, impacting sensitivity • Robustness of sensor-enabled stripping of target metal ions in river water
