(326d) Effect of Synthesis Condition of Thermoresponsive Polymer/Magnetic Particle Composite on Its Cu(II) Ion Recycling Property
In this study, in order to improve the heavy metal ion recovery property of the adsorbent, the effect of synthesis condition of the adsorbent on its heavy metal ion recovery property was examined in detail. In the experiment, the thermoresponsive adsorbents were synthesized using various technique such as âgrafting toâ method, and âin situâ method, modified co-precipitation method and the resulting heavy metal ion recycling property was examined. The results showed the maximum amount of immobilized copolymer on the magnetic particle and Cu(II) adsorption in the case of âin situâ method were 2.2 and 1.7 times higher than those in the case of âgrafting toâ method, respectively. In addition, the adsorbent prepared by âin situâ method demonstrated highest value in the recycled Cu(II) amount through temperature swing compared to other several of thermoresponsive âgel typeâ adsorbents.
