Selective Removal Methods and It's Fabrication Method for Uranium Ions, Radioactive Ions and Salts in Liquid Waste by Electrosorption Technique

摘要

The present invention relates to a process for the preparation of the adsorbent material used in the uranium ions in the waste liquid by the electric absorption, a radionuclide, a metal ion and salt selection and removal method here.; An object of the present invention is the low concentration of the uranium ions co-exist with a high concentration of the chemical salt, radionuclide, metal ions and salts are selectively absorbent distilled runaway emission level of 1 ppm or less capable of emitting a waste fluid to the normal liquid effluents of the AEA uranium, radionuclides, and to provide a manufacturing method of adsorbent material used in the selected removal of the waste liquid by the electric adsorption process and this can be processed to a metal ion and salt concentration, the present invention hundreds of the high concentration of the chemical salt selected removal of uranium present in a ppm concentration is of course also in the process of the present waste liquid simply operation is simple as a way to remove selected radionuclide (or ion species and the salt component) by the potential control and simple availability potential reversal At the same time the concentration of the component by removing only the desorption of adsorbed contamination by radionuclides used to continuously play back the electrode material by adsorption There are technical and economic advantages that can be.
