ABSTRACT:
A method and apparatus for determining the concentration of chemical species in solution. The method involves passing the solution through a cell containing an ion-selective electrode. Measurement is carried out following suppression of interfering materials, under turbulent flow conditions. The apparatus preferably includes microprocessor controlled instrumentation and is particularly useful for the on-line determination of the concentration of copper(II) ions in electrolyte solutions.
