Abstract
Summary
A number of structurally related new unsymmetrical monoamides with different substituting groups, N-methyl-N-decyloctylamide (MDOA), N-methyl-N-decyldecanamide (MDDA), and N-methyl-N-decyldodecanamide (MDDOA), were synthesized. The extraction of U(VI) from nitric acid medium by the synthesized monoamides diluted with toluene was investigated. The effect of nitric acid concentration, sodium nitrate concentration, extractant concentration and temperature on the distribution ratio was studied. The stoichiometry of the main extracted species confirms to UO2(NO3)2·2A (A, amidic extractant). The values of the thermodynamic parameters were determined and the extraction reactions were found exothermic. The IR spectral study was also made of the extracted species.
