Abstract
PURPOSE: An adsorbent comprising magnetic fine particles as nuclei and uranium adsorbent deposited over the surface of the fine particles, which is capable of easily separating and grasping uranium (U) from the sea water or an U-containing solution and also is easily recoverable after separating U adsorbed.
CONSTITUTION: Average grain size of approx. 0.01 to 5 micron of fine magnetic particles, e.g., magnetite, gamma-Fe2O3, and other ferromagnetic ferrites are dispersed by an ultrasonic wave irradiation in distilled water, ad then the fine magnetic particles suspension is mixed with stirring by the addition of an aqueous solution of one or several species of meral salts as adsorbents, e.g., titanium sulfate, TiCl4, MgCO3, MnSO4, etc. In this case, the metal salt is added in a mixing ratio of approx. 0.5 to 5 in terms of metal on the basis of the fine magnetic particles. Subsequently, hydrolysis after pH regulation and other usual precipitation operation, etc. are made to deposit them on the surfaces of the fine magnetic particles. These particles are separated by an appropriate magnetic separator, washed, and then dried.
