  The present invention provides a novel process for the removal and recovery of radionuclides from waste waters and process streams. The process of the present invention utilizes a combination of a supported liquid membrane (SLM) and a strip dispersion to improve extraction of the target species while increasing membrane stability and reducing processing costs. Additionally, the invention provides a family of new extractants, alkyl phenylphosphonic acids, for the removal and recovery of radionuclides and/or metals, including the use of the new extractants in the process. The new extractant selectively removes radionuclides and metals from the feed stream to provide a concentrated strip solution of the target species.

  本发明提供了一种从废水和工艺流中去除和回收放射性核素的新型工艺。本发明的工艺利用支撑液体膜（SLM）和带状分散体的组合来改善目标物质的萃取，同时提高膜的稳定性并降低处理成本。此外，本发明还提供了一系列新型萃取剂--烷基苯基膦酸，用于去除和回收放射性核素和/或金属，包括在工艺中使用新型萃取剂。新萃取剂可选择性地从进料流中去除放射性核素和金属，从而提供目标物质的浓缩带状溶液。

  The present invention provides a novel process for the removal and recovery of target species, such as metals, radionuclides, penicillins, and organic acids, from waste waters and process streams. The process of the present invention utilizes a combination of a supported liquid membrane (SLM) and a strip dispersion to improve extraction of the target species while increasing membrane stability and reducing processing costs. The present invention also provides an SLM, embedded in a microporous support material with an interfacial polymerized layer or layers. Additionally, the present invention provides novel classes of extractants and methods of manufacture for the extractants. The new classes of extractants include alkyl phenylphosphonic acids and dialkyl phosphoric acids. The method for manufacturing the dialkyl phosphoric acid extractants includes mixing phosphorus pentasulfide with an alcohol, followed by hydrolysis of the intermediate reactants with a mineral acid.

  The reaction of phosphonic dichlorides with a mixture of benzyl alcohol and an aliphatic alcohol affords a mixture of the corresponding dibenzyl phosphonate, dialkyl phosphonate, and alkyl benzyl phosphonate which is easily separated by column chromatography to give the pure components. Cleavage of the dibenzyl phosphonate by catalytic hydrogenation affords the phosphonic acid whereas cleavage of the alkyl benzyl phosphonate under the same conditions affords the alkyl hydrogen phosphonate (monoester).
