Abstract
PURPOSE: To measure NH3 concentration simply and rapidly, by using the microbial electrode, where nitrification bacteria to oxide NH3 and consume oxygen is sealed, between the partition film of the oxygen electrode and the gas permeating film and so on covering this partition film, and by allowing this electrode to contact with liquid to be inspected.
CONSTITUTION: A microbial electrode consists of partition film 5 of the oxygen electrode, gas permeating film or cation permeating film 4, platinum cathode 6, Al anode 7, and so on, and microbial bacteria layer 1 where nitrification bacteria such as nitrosomonas europaea ATCC19718 and nitrobacter aziris ATCC14123 to oxidize NH3 and consume oxygen is caused to adhere and fixed to CaCO3 is provided between partition film 5 and gas permeating film or cation permeating film 4 covering film 5. This microbial electrode is brought into contact with inspected liquid to measure the reduction speed of the electrode current and the balance current, and the proportional relation between the reduction speed or the balance value of the current and NH3 concentration in inspected liquid is utilized to measure NH3.
