Abstract
The main regularities of membrane extraction of americium under condit ions of different redox potentials in aqueous phases have been studied . The physico-chemical model of the process including steps of americi um oxidation in feed solution, extraction by membrane, partial reducti on on membrane surface, trans-membrane diffusion and reextraction to s trip solution has been developed. The calculation of reduction rate co nstant on membrane surface has been carried out.
