| titleOfInvention | Cation exchange fiber filter comprising polyacrylonitrile family fiber |
| abstract | The present invention relates to a cation exchange fiber filter capable of purifying and recovering heavy metals, organics and radionuclides present in the air, and a method for preparing the same. More specifically, the polyacrylonitrile-based fibers are converted into hydrates of hydrazine and sodium hydroxide. The present invention relates to a highly efficient and inexpensive cation exchange fiber filter which is sequentially treated to remove harmful compounds by adsorption and cation exchange reactions and a method of manufacturing the same. |
