Applications of Electrochemical Sensors in the Analysis of Inorganic Substances

Ammonium-selective, membrane electrodes [1,2] as well as an amperometric biosensor [3] are proposed for the assay of ammonium ion. For the ionselective membrane electrodes, the main interfering ion is potassium. The utiliza­ tion of an enzymatic reaction can improve the selectivity of the electrochemical sensor.
