A METHOD FOR PREPARING ABSORBENTS FOR TREATMENT RADIOACTIVE WASTEWATER AND A METHOD FOR TREATING RADIOACTIVE WASTEWATER USING THEM

摘要

PURPOSE: A method for manufacturing an absorber and a method for treating radioactive waste are provided to treat radioactive waste contaminated with single or multi-component radionuclide by using hydroxyapatite of a nano size. CONSTITUTION: CaCl2 of 3 - 6g and K2HPO4 of 2 - 5.5g are inputted to simulated body fluid of 1 liter. Mixture is stirred at 30 to 40 degrees centigrade for 12 to 36 hours. Solid liquid is separated through a centrifugal method after stirring the mixture. Precipitate is cleaned with distilled water and ethanol and is treated with an ultrasonic wave.
