This work was focused on the applicability of a new diamide N,N'-dimethyl-N,N'-dioctylsuccinamide (DMDOSA) employing cyclohexane as the diluent to extract Dy(III) and Sm(III) from nitric acid solutions. The extraction from HNO 3 was investigated by distribution measurements. The stoichiometry of the predominant adducts of DMDOSA with HNO 3 is 1:1 (HNO 3 .DMDOSA) under the studied conditions. The effect of the concentrations of nitric acid, lithium nitrate and extractant on the distribution ratio was investigated. An IR spectral study was also made of the extracted species.
