Double charge composite materials for contaminant removal and methods of making the same
| DWPI Title: Removing ionic contaminant from fluid involves introducing solution comprising material consisting essentially of anionic layered double hydroxide with cationic clay material into fluid to form flocculant adsorption material having oppositely charged components |
| Abstract: A method for removing a contaminant from a fluid is provided. A positively charged layered double hydroxide is combined with a negatively charged clay material to form adsorption material. The adsorption material is contacted with an aqueous solution containing the contaminant to adsorb the contaminant onto the adsorption material. |
| Use: Method for removing ionic contaminant from fluid. |
| Advantage: The method produces product which has higher radionuclide sorption capacity and greatly reduces colloidal release. |
| Novelty: Removing ionic contaminant from fluid involves introducing a solution comprising a material consisting essentially of an anionic layered double hydroxide with a cationic clay material into the fluid to form a flocculant adsorption material having oppositely charged components, where the fluid comprising ionic contaminant, absorbing the contaminant onto the flocculant adsorption material, the anionic layered double hydroxide comprises a crystalline, layered double hydroxide metal complex comprising an interlayer anion. |
