Description

The transport of europium has been studied through a supported liquid membrane (SLM) impregnated with dihexyl-N,N-diethylcarbamoylmethylphosphonate (CMP). Europium was effectively extracted from the perchlorate solution into SLM, but was insufficiently stripped to a dilute acid solution. The addition of 1-decanol improved the stripping process, and quantitative transport of europium was achieved. By the combination of two SLM systems consisting of diisodecylphosphoric acid and CMP, europium was transported from the feed solution (0.1 M HNO3) through the intermediate solution (1 M HClO4 + 4 M NaClO4) to the product solution (0.1 M HNO3) and effectively concentrated by a factor of about 20
