Differential electrolytic potentiometry, a detector in flow injection analysis for precipitaton reactions.
The application of differential electrolytic potentiometry as a detection system in flow injection analysis for precipitation reactions is described. Different combinations of electrodes were investigated. The optimum conditions for the current density and the flow rate were elucidated. In the case of chloride, an Ag/AgCl-Pt pair was found to be successful. For iodide a combination of Ag-Pt electrodes was found to give good results. The relation between the concentration of analyte and the measured signal was found to be linear.
