Abstract
The applicability of differential electrolytic potentiometry as a detection system in flow injection analysis is investigated. A computer- controlled injector which delivers precise volumes of sample solutions in a reproducible manner was developed. Conditions such as current density employed, the concentrations of the solutions used and the flow rate were optimized. Chloride in water was determined by means of this system. The relation between chloride concentration and the measured signal was found to be Nernstian for solutions of concentrations above 6 μg ml-1 chloride. For solutions below this concentration, the relation is linear.
