High molecular polymer, preparation method and application as fly ash chelating agent |
| abstract |
The invention belongs to the technical field of environmental protection, and particularly relates to a high molecular polymer, a preparation method and an application as a fly ash chelating agent. The invention provides a high-molecular polymer, which is obtained by reacting 2,5-dithiodiurea with formaldehyde; the high-molecular polymer has excellent chelating ability for heavy metal ions such as Pb 2+ , which can be used as a heavy metal ion chelating agent to stabilize heavy metal ions in environmental pollutants such as fly ash. |
