Abstract: |
The alkali modification of fly ash and the application of modified fly ash to deal with Arsenic containing wastewater were investigated. The results show that 98.88% Arsenic ions in wastewater can be removed by modified fly ash.Doped iron can further improve the adsorption performance. |
