摘要：

Extraction of Am(III), U(VI), and Pu(IV) from HCl solutions with solutions of diphenyl(dibutylcarbamoylmethyl)phosphine oxide in dichloroethane and m-nitrobenzotrifluoride was studied. The curves of the Am(III) and U(VI) extraction as a function of the acid concentration pass through a minimum at [HCl] = 1 M, followed by a steep ascent at the acid concentration increased further. The logarithmic dependences of the distribution factors on the extractant concentration are nonlinear, with the slope of the upper portions close to 2 for Am(III) and 1 for U(VI). Pu(IV) is extracted noticeably worse than U(VI). A significant anomalous aryl strengthening effect is observed in HCl solutions.
