Treatment of Radioactive Waste by Ion Exchange
This paper describes a preliminary study of the absorption and desorption of ion exchage processes involving radioactive isotopes.
Cation exchange DOXEX 50-x8 （H） removes the bulk of radioactivity of alkali and alkali earth metal, Co, Mn in pH 10, Fe, Cu in pH 7, and Fe, Cr in pH 2 solutions. But anion exchange Amberlite IRA-400 (OH) usually absorb it in neutral were best.
Regenerant of 5.6 N nitric acid for cation and 1 N sodium hydroxide for anion were required 3 to 5 times of resin bed.
Treatment of fission product of 10-4 c/ml （267.9 p.p.m. as NaCl） with mixed bed(8.3Φ×100 ㎝) flowing at a rate 40 l/hr provides complete removal of various impurities and give an effluent having an activity level below 10-7 c/ml (0.0 p.p.m. as NaCl)
