In ,acidic, conditions, the amount of available NH 3 is extremely low. A 1974 study by Suzuki and colleagues demonstrated that the AOB N. europaea is only able to use ammonia, rather than ammonium, which has long been considered the key reason why AOB are unable to grow in ,acidic, environments (Suzuki, Dular and Kwok 1974).

electro-catalytic oxidation of organic ,wastewater, is limited because of high electric power consumption [3–6]. Also, there are also some problems with photo-catalytic water splitting to produce hydrogen and photo-catalytic degradation of ,wastewater,, such as poor use of visible light and low light quantum efficiency [7–10].

speculated,, from the experimental results with molecular orbital (MO) simulation for frontier electron density. The primary photocatalytic degradation reaction keeps a pseudo first order kinetic law. The activation energy (E a) and half-life (t 1/2) are 20.6 kJ/mol and 1.4 min, respectively. The fenitrothion ,wastewater, photocatalytic treatment may
