| Research Abstract |
We have investigated the adsorption property of hydrophobic useful substance by using the thermosenstive gel particulate of the average diameter 400nm, that was compounding with the magnetic particulate of diameter, 50nm and the thermosensitive poly -Nisopropylacrylamide (pNIPA) gel. The improvement of separation efficiency of the particle was also investigated to find that an increase of the ratio of pNIPA in the gel particle was effective. It became clear that the hydrophobic useful substance could be separated from solution by the temperature swing across the transition temperature (32℃)
