1. In an amperometric method of determining the concentration of arendiazonium salts in a diazocoupling reaction mixture, the method comprising the steps of applying a DC voltage across a tellurium measuring electrode in contact with the mixture and a reference electrode so that only ions of arendiazonium salts in the mixture are reduced on the surface of the measuring electrode, measuring the resultant current through the measuring and reference electrodes, and periodically cleaning the measuring electrode.
