Abstract
A flow-type cell for simultaneous determination of fluorine, chlorine, nitrate, and ammonium ions has been developed. The dynamic parameters of ion-selective modules of the cell have been studied and the condit ions of in-flow potentiometric measurements have been optimized. In an alysis of synthetic solutions of composition chemically close to drink ing water, the standard error was less than 0.02 in the determination of nitrates, fluorides, and chlorides, and 0.04 in the determination o f ammonium.
