Removal of Low Levels of Ammonium Ion From pacecraft Recycled Water 1999-01-2119
Poly (vinyl chloride) (PVC) matrix membranes which incorporate the ionophore nonactin have been evaluated as cation exchange membranes for ammonium ion transport in an electrolytic cell configuration. Interest exists for the development of cation selective membranes for removal of low levels (<200ppm) of ammonium ions commonly found in recycled effluent streams in such diverse applications as expected in a Space Station and commercial fisheries. Ammonium ions are generated as a decomposition product of urea and over time build up in concentration, thus rendering the water unsuitable for human consumption. Nonactin is commonly used in a PVC matrix for ion-selective electrodes.
