摘要: Extraction of Am(III) was performed at the interface organic-aqueous two-layer flow in a micro-channel having an asymmetric cross section. A solution 3 mol/dm3 nitric acid containing 243Am(III) and octyl(phenyl)-N,N-diisobutylcarbamoylmethylphosphineoxide diluted with n-dodecane were introduced into microchannel as aqueous phase organic phase, respectively. The two phases formed stable parallel to sidewall microchannel, they separated from each other divergence point microchannel. extraction reaction proceeded phases, reached equilibrium state while passed through
