【 摘 要 】

A ferrofluid has been obtained from magnetite and beta-cyclodextrin, with the formation of an inclusion complex. The magnetite and beta-cyclodextrin complex was characterized by FTIR spectroscopy, X-ray diffraction, thermal analysis (TG/DTA), transmission electron microscopy (TEM) and atomic absorption spectroscopy. As far as we know, this is the first report on an inclusion compound between a metal oxide and cyclodextrins.
