摘要
In this paper, a boron-doped diamond film, a new type of environmentally friendly electrode, was used as the sensing electrode. The analysis of trace metal cadmium was carried out by ultrasound-assisted square wave anodic stripping voltammetry. The influence of some experimental variables such as the supporting electrolyte, accumulation potential and accumulation time were investigated. Under the optimized conditions, the stripping peak currents showed a good linear relationship with the Cd2+ concentration ranging from 19.80 to 243.9 mu g L-1 with a detection limit of 1.0 mu g L-1. The effects of potential interfering ions were also studied, and the method was successfully applied to the determination of Cd2+ in real-water samples.
