Abstract
Electrochemical detection of trace arsenic(III) in aqueous phase was studied with a porous gold (PAu) electrode, which was prepared by paper-based templating method. Square wave voltammetry was performed in As(III) solutions. The limit of detection of 0.1 ppb was obtained with a linear detection range of 0.1–14 ppb, which complies with the regulations for As(III) content in drinking water. The analysis of roughness factor and diffusion coefficient showed that the porous structure of the PAu electrode might have a stronger contribution to improving the sensitivity and selectivity of the target ion, compared to bulk gold electrode.
