Abstract
Official abstract text for this publication.
The present invention relates to a chitosan-titanium composite, a preparation method and use thereof, and more particularly, a chitosan-titanium composite capable of effectively adsorbing and desorbing 68 Ge/ 68 Ga by combining small molecular chitosan with titanium metal oxide to increase adsorption reactivity to 68 Ge and 68 Ga desorption reactivity, and a preparation method and use thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A method for manufacturing a chitosan-titanium composite, the method comprising: a step of preparing a first solution by adding small molecular chitosan powder to an acetic acid solution; a step of preparing a second solution by adding a titanium solution to the first solution; a step of forming a bead by dropping the second solution into ammonia water; and a step of washing, drying and sintering the bead, wherein the small molecular chitosan has a molecular weight of 50,000 to 190,000 Da, and wherein the bead has a diameter of 200 to 400 μm. 2 . The method according to claim 1 , wherein in the step of forming beads by dropping the second solution into aqueous ammonia, the falling flow rate of the second solution is adjusted to 5 to 10 mL/min. 3 . The method according to claim 1 , wherein the sintering step is performed at 400 to 500° C. for 6 to 8 hours. 4 . The method according to claim 1 , wherein the chitosan-titanium composite is used for the adsorption of radioactive isotope. 5 . The method according to claim 4 , wherein the radioactive isotope is 68 Ge.
