Results of the measurements of the exchange capacity and K{sub d} values for ReO{sub 4}{sup {minus}} on Reillex{trademark}-HPQ as a function of nitric acid and hydroxide concentration, temperature, and ten months time will be reported. Results of the breakthrough volumes for UO{sub 2}{sup 2+} on Reillex-HPQ chromatography columns as a function of carbonate ion concentration in high nitrate ion concentrations and various column sizes will be reported. Individual sections of this report describe the following: the sorption behavior of ReO{sub 4}{sup {minus}} on the Reillex-HPQ between pH 2 and 12 in 1.00 M NaNO{sub 3}; results of the measurements of the K{sub d} values for ReO{sub 4}{sup {minus}} on Reillex-HPQ and on Reillex-HP as a function of nitrate and hydroxide ion concentrations; the sorption behavior of ReO{sub 4}{sup {minus}} on Reillex-HPQ resin in base with time as a variable; the results of the early attempts at determining the K{sub d} values for Na{sub 4}UO{sub 2}(CO{sub 3}){sub 3} on Reillex-HPQ resin; and the breakthrough of UO{sub 2}(NO{sub 3}){sub 2} in varying nitric acid solutions on Reillex-HPQ columns.
