摘要

A glassy carbon electrode (GCE) modified with multiwall carbon nanotubes (MWCNTs) for electrochemical square-wave stripping voltammetric (SWV) determination of antimony (III) was introduced. Various experimental parameters, such as the amounts of carbon nanotubes, the deposition potential and time, the electrolyte solution, etc, were thoroughly optimized and discussed. Under the optimum experimental conditions, the MWCNTs-modified GCE exhibited well linear behaviour in the antimony(III) concentration range from 0.04 to 0.26 mg/L (R=0.9983) with a detection limit of 3.20×10~(-4) mg/L (S/N=3) under a 360 s accumulation. The proposed electrode also exhibited encouraging properties for measurements of simulated water samples.
