超音波를 利用한 Th, U, Ce의 鹽基性 沈澱分離

다국어 초록 (Multilingual Abstract)

Basicity separation of Th, U and Ce under ultrasonic fiold was studied in Comparison with the Conventional basicity separation under mechanical stirring in the pure Th, U, Ce nitrate Solutions. The experiment of ultrasonic field was acted at the various frequency. intensity and Solution Concentration in other fixed Conditions. It has been found that the intensity of ultrasonic has many effects on the pH range of separation according to the increasing intensity, and that the frequency and the relative ratios of solution Concentracion have little change on the separation. But it is possible to separate solid from liquid very easily because of Coagulation of particles to the increasing frequency.
In th e Condition of 400KC, 4.1 W/㎠ of ultrasonic, the advantages of separation were the improved grade of 10% and recovery of 40% in the th products, and the grade of 20% and recovery of 55% in the U products than the conventional method.
According to these results, basicity separation by ultrasonic radiation can be applied to the Crude Separation of monazite which is used at present to high purity and recovery without other refining process.
