摘要：

An on-line flow system for anodic stripping voltammetry has been investigated for the pre-concentration of cadmium and copper and the separation of copper from a sodium matrix for detection by inductively coupled plasma atomic emission spectrometry and inductively coupled plasma mass spectrometry (ICP-MS). Good signal enhancement was obtained with pre-concentration of moderate sample volumes. Matrix elimination of more than 99% was possible for reasonably high concentrations of undesired matrix elements, namely Na and U. Isotope ratio data for ICP-MS indicated that the interference of ArNa + on Cu+ at m/z 63 could be minimised.
