Description
The extraction of uranyl nitrate by the novel extractant N,N'-dimethyl-N,N'-dioctylsuccinylamide (DMDOSA) from aqueous nitric/nitrate solutions was investigated. The effects of concentration of HNO3 and DMDOSA on the U(VI) extraction distribution was studied. The extraction mechanism was established and the stoichiometry of the main extracted species was confirmed to be UO2(NO3)2 x 2DMDOSA. The value of ΔH of the extraction is -23.9±1.7 kJ x mol-1. A IR spectral study of the U(VI) extracted species was also made. (author)
