A computer-controlled voltammetric flow-injection system

Voltammetric measurements are done with a laboratory-made digital voltameter; the detector is a thin-layer cell ith a glassy carbon working electrode. Three e-way and one 8-way magnetic valves are used to switch the flows to the detector. the 8-way valve can also be used as the injection valve. An ABC-80 computer controls the system, with a single-chip microcomputer as slave to control the voltammeter. The system was tested in continuous monitoring and in flow-injection determination of iodide. An authomatic stripping voltammetric method for the determination of chloride is also described.
