Abstract: A wastewater treatment system has been developed by using a mixture of ammonium-insoluble tannin (TANNIX, this is the trademark of an adsorbent made by Mitsubishi Nuclear Fuel Co. Ltd) and mixed (strong acid cation exchanger and strong base anion exchanger) ion exchange resin (MIX) for the selective separation of transuranium isotopes, including Pu, Am, Cm, and U, as well as fission and radioactive corrosion products from boric acid solution (pH ∼ 4.1). The equilibrium and fixed bed sorption experiments resulted in K_d values of 10⁴–10⁵ ml/g, and decontamination factors of 1,000, with a breakthrough point between 1500 BV and 5000 BV of accumulated volume.
