There are more anionic than cationic impurities in the moderator, due to nitric acid and CO/sub 2/. The principal impurities removed by the anion resin are NO/sub 3//sup -/, dissolved CO/sub 2/, and SO/sub 4//sup - -/. From an exhausted mixed-bed deionizer, H/sub 2/CO/sub 3/ is the first component eluted. Nitrate acts as the elutriant, but it does not displace SO/sub 4//sup - -/. No evidence for gross release of Cl/sup -/ was found in minipure resin columns run past initial depletion. I/sup 131/ is released after elution of H/sub 2/CO/sub 3/ has proceeded for a time. The cationic impurities include Al, Fe, Ca, Mg, Mn, Cr, and Co, and the radionuclides Na/sup 24/, Np/sup 239/, and Mn/sup 56/. In addition to the ionic impurities, particulate matter, consisting mainly of iron and aluminum oxides, is filtered out by the resin to the extent of about 1 wt % of the moist resin. Pressure surges will result in release of this material from the loaded column back into the effluent stream.
