Title:
METHOD FOR REMOVING CESIUM ION IN BLOOD
Document Type and Number:
WIPO Patent Application WO/2018/090406
Kind Code:
A1
Abstract:
A method for removing cesium ions in blood belongs to the field of blood purification and nuclear medicine emergency. The method comprises the following steps: in the presence of polyethylene glycol, an acetate salt and an anionic surfactant, adding a trivalent ferric salt and an aqueous ferricyanide solution into ethylene glycol, and performing a closed reaction at a temperature of 180-200℃, so as to obtain magnetic Prussian Blue particles; dispersing the magnetic Prussian Blue particles in blood; and after adsorption equilibrium, separating from blood the magnetic Prussian Blue particles that have adsorbed cesium ions. The adsorbent having high selectivity and biocompatibility prepared by the method can be used for adsorbing cesium ions in blood. The method is characterized by being efficient and rapid. Cesium ions in blood can be more accurately measured using ICP-MS.
