Abstract
|
|
|
|
The functional group of commercially available ion exchange resins is known to be NMe₃, of which selectivity prefers SO₄^(2-) ion to NO₃^(-) ion. Based on the fact that SO₄^(2-) ion occupies a larger space than NO₃^(-) ion in the chemical compounds, a new ion exchange resin was developed by the use of NEt₃ and N(CH₂CH₂OH₃)₃ as functional groups and subsequently determined the physicochemical properties of the newly developed ion exchange resin. As indicated at the results, the selectivity of this ion exchange resin preferred NO₃^(-) ion to SO₄^(2-) ion.
