| 内容記述 | 2-Ethylhexyl phosphonic acid mono-2-ethylhexyl ester (PC-88A), which is an effective extractant of Co(II), was microencapusulated by two step crosslinking of sodium alginate by Ca2+ ion and polyvinylalcohol by glutaralde. Globular microcapsules containing PC88-A droplets with the diameter around 4 mm were successfully prepared and had a relatively high strength. The microcapsules had smooth surface with large pores and many droplets of PC-88A in their inner side. The percentage content of PC-88A in the microcapsules was 18 % for wet sate of the microcapsule. The extraction of Co(II) using the microcapsules containing PC-88A sharply increased at pH values greater than 5. Zn(II) extracted in the microcapsules was successfully back-extracted at pH values less than 4. No destruction of the microcapsules was observed during the repeated use of several times. |
