Sulfonic acid Modified Periodic Mesoporous Organosilicas Adsorbent of Application as Metal Ion Collector in Wastewater |
| 초록 |
The modified periodic mesoporous organosilicas have been successfully synthesized through bissilylated urea bridged organosilica and modified using chlorosulfonic acid in chloroform. The effect of solution pH, sorption time, temperature and initial metal ion concentration onto metal ions sorption was investigated. The characteristics of the sorption process were evaluated by using the Brunauer-Emmett-Teller(BET) adsorption isotherms. The sorption of metal ions onto modified periodic mesoporous organosilica correlated well with the Brunauer-Emmett-Teller(BET) type adsorption isotherm and adsorption capacities. From the Brunauer-Emmett-Teller(BET) adsorption isotherms, it was concluded that chemical interactions and chelating effects were playing an important role in the sorption of metal ions onto sulfonic acid modified periodic mesoporous organosilicas. |
