Evaluation of New Macroporous Resins for the Removal of Uranium and Plutonium from Waste Streams

摘要

Organic ion exchange resins were evaluated for 238Pu(IV), 238Pu(VI), and 233U(VI) removal from water. The capacity of the resins and equilibrium co efficients (Kd) were compared with each other and to bone char - an inorganic adsorbent consisting of hydroxyapatite (HAP) for which data is available. Bone char gave the best results for the removal of 238Pu(IV), Amberlite XE279 (one of the new macroporous resins) gave the best results for 238Pu(VI), and another macroporous resin, Dowex-MSA-1, gave good results for 233U(VI). Kd values were shown to be a function of pH.
