Stripping analysis is a sensitive, precise, and economical electroanalytical technique for measuring heavy metals (1, 2). As a result of its inherent sensitivity, the technique is widely used for direct measurements in environmental, industrial, and clinical samples. The need for rapid monitoring of trace metals has led to the development of various flow systems for stripping voltammetry (3-7). Such on-line systems offer various advantages for many practical situations. For example, flow measurements, effected in the natural environment, offer the option of continuous surveillance (3). Automated flow systems, based on the flow injection or automated analyzer principles (4, 5), are especially suitable for clinical or quality control applications.In this paper, we describe a number of advantages obtained by using a large volume wall-jet detector in on-line stripping measurements. Various electrode geometries have been used in anodic stripping flow systems. These includemainly cells in which the solutionflows through a tubular electrode (3)
