Abstract
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 68Ge/68Ga by combining small molecular chitosan with titanium metal oxide to increase adsorption reactivity to 68Ge and 68Ga desorption reactivity, and a preparation method and use thereof.
Claims5
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.
