Abstract

It was successfully demonstrated that ammonia concentration in water can be determined easily with a remarkably wide dynamic range of 5 orders of magnitude by measuring the photocurrent generated by ammonia in a photoelectrochemical cell composed of a nanoporous TiO2 photoanode, an O2-reducing Pt cathode and a UV-LED (ultra-violet light-emitting-diode) light source.
