| Abstract: The metal-free carbon materials were obtained by a facile KOH activation and pyrolysis process from inexpensive and readily available pomelo peels, and possessed honeycomb-like nanostructures with a high specific surface area of 1 055 m2·g-1 and a high graphitization degree. A porous activated carbon (PAC) material modified electrode was utilized as the working electrode for the simultaneous detection of Cd2+, Pb2+, and Cu2+ using square-wave anodic stripping voltammetry (SWASV) and exhibited high sensitivity, repeatability, stability and a low detection limit. The interconnected micropores and mesopores act as efficient ion-transfer channels and provid active surface areas with high accessibility, which serve as transport highways to accelerate mass diffusion and significantly promote exchange efficiency. High graphitization degree increases the electrical conductivity of the material and accelerates electron transport. |
