Heavy metal poisoning has a life-threatening impact on the human body to aquatic ecosystems. This necessitates designing convenient green methodology for fabrication of an electrochemical sensor that can detect heavy ions efficiently. In this study, boron (B) and nitrogen (N) co-doped laser-induced porous graphene (LIGBN) nanostructured electrodes were fabricated using direct laser writing technique. The utilised individual simultaneous detection lead (Pb2+) cadmium (Cd2+) square wave voltammetry technique (SWV). synergistic effect B N co-doping results in improved sensing performance electrode with better sensitivity 0.725 µA/µM Pb2+ 0.661 Cd2+ ions, respectively. Moreover, shows low limit 0.21 µM 0.25 wide linear ranges from 8.0 80 high linearity R2 = 0.99 case detection. rapid facile method fabricating heteroatom-doped opens new avenue studies various hazardous ions.
