Short description: |
A material, called PANSIL, has been developed for the treatment of uranium-contaminated groundwater using permeable reactive barriers. It is a tailored ligand system that selectively removes a contaminant from solution. It is highly effective at sequestering UO22+ when the pH is between about 5 and 8 and can preferentially sequester UO22+ from solutions that are typical of the groundwater from mine tailings sites. Uranium sequestration capacity exceeds 4000 mg of UO2 per kg of PANSIL at pH 4.5 when the dissolved UO22+ concentration is greater than 300 mg/L. PANSIL largely retains the permeability and strength of the sand employed and therefore has suitable engineering properties for permeable reactive barrier applications.
