  • Inorganic-organic hybrid gels for extracting species such as lanthanides and actinides, and their preparation
    Patent number: 6667016
    Abstract: Inorganic-organic hybrid gels can be employed to extract chemical species such as lanthanides and actinides and their preparation. The gels include a network of inorganic components with the formula: where M is Si, Ti, Zr or Al, wherein organic molecules which can complex the species to be extracted are integrated, with each organic molecule being covalently linked to one or several M atoms in the network. The network is made by a sol-gel process from metallic alkoxides functionalized with complexing groups (amino, ether, hydroxy, amido, pyridino and bipyridino), capable of extracting metals such as lanthanides and actinides.
