| Outline of Final Research Achievements |
A mesoporous silica (MS) adsorbent with temperature sensitivity and magnetism was synthesized. At first, hematite was precipitated on the MS surface, and then a MS coated with magnetite (MMS) was produced by reduction. Furthermore, this MMS was coated with PNIPAM (Amino-PMMS). Results of thermogravimetry showed the amount of PNIPAM in the Amino-PMMS was around 2.4 wt%. Also, the Amino-PMMS was well attracted by a magnet. The Amino-PMMS adsorbed around 0.19 mmol/g of methyl orange (MO) at room temperature, whereas it adsorbed only around 0.08 mmol / g of MO at 42°C (above the lower critical solution temperature of PNIPAM). This indicates that the synthesized Amino-PMMS is a temperature-responsive adsorbent.
