Abstract:
The potential applicability of a pyrolytic carbon film electrode in the differential-pulse anodic-stripping voltammetric determination of cadmium and lead in sea-water is demonstrated. The performance at the 10−10M level is compared with that of a satisfactory glassy-carbon electrode. The two types of electrode display comparable behaviour in anodic-stripping voltammetry, but the pyrolytic carbon film electrode needs less pretreatment.
