Surface Modification of Polymeric Microbeads with Sulfonamide Derivatives for Water Softening Application |
| 초록 |
Water softening is an important procedure since ions cause significant problems with maintenance of equipments or facilities. In this research, sulfonamide-derived cation capturing system is suggested as an alternative to relieve the limitation of commercialized system. Sulfonamide derivatives show a sharp transition from charged to uncharged form at certain pH, which alleviates the condition of regeneration. Moreover, chemical modification of sulfonamide had been fully established so that ion selectivity can be easily modulated by introducing various sulfonamide derivatives. Four types of sulfonamide derivatives were selected as candidates in our research and introduced on the surface of polystyrene microbeads. The surface modification was confirmed by FT-IR analysis, and their calcium ion capturing capacities were verified. Finally, the most regenerative type of sulfonamide in the moderate acidic condition was determined. |
