Extraction of pollutants by inorganic chelation |
摘要 |
In a method for removing an inorganic pollutant from contaminated waters, the pollutant is extracted by contact with a chelating agent to form a metal chelate complex. The metal chelate complex is then contacted with a regenerating agent which regenerates the chelating agent for reuse and prepares the inorganic pollutant for removal.
