Combined supported liquid membrane/strip dispersion processes and extractants |
| abstract |
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. |
