Abstract:
1. A uranium ion exchange adsorption method using ultrasound, comprising: providing a slurry including uranium ions, sulfuric acid, and an ion exchange resin in a reaction bath, wherein the reaction bath is contained in a bath container; and stirring the slurry in the reaction bath while applying ultrasound to the reaction bath to allow the uranium ions to be adsorbed onto the ion exchange resin through ion exchange adsorption, wherein the slurry is stirred at a temperature of 20 to 40° C. during ion exchange adsorption, wherein the slurry is adjusted to have a pH of 2 to 6 during ion exchange adsorption, wherein the slurry is stirred at a rate of 200 to 450 rpm to prevent the slurry from flowing out of the reaction bath, wherein the ultrasound is applied at an output power of 10 to 90 W, wherein the ultrasound is applied using an ultrasonicator with a tip, and wherein the tip is inserted into the bath container surrounding the reaction bath to prevent the ion exchange resin from being damaged.
