Title:
ADSORBING METHOD OF URANIUM
Document Type and Number:
Japanese Patent JPS6114135
Kind Code:
A
Abstract:
PURPOSE: To obtain a high-concn. soln. contg. uranium with a high degree of adsorption by passing an acidic soln. contg. uranium through an uramium adsorbent adsorbed with uranium and recovering only the discharged soln. contg. uranium.
CONSTITUTION: An uraium adsorbent (for example, titanic acid) adsorbed with uranium is packed into a column and an uranium-contg. acidic soln. having 0.4W2N concn. is passed therein from the lower part. The discharged soln. of just after the starting of desorption in which uranium of ≥7pH or ≥20mω electric conductance is not contained is removed and only the discharged soln. contg. uranium of ≤7pH or ≤20mω electric conductance is recovered.
