| Abstract: | Separation of ammonia-nitrogen from the wastewater with D2EHPA as extractant is carried out with supported liquid membrane. The kinetics of extraction can be expressed as a function of acidity of the feed solution and the concentration of membrane carries. The coupled-transport model describing the permeability coefficient of NH4 is derived. |
