Adsorption of COD and Ammonia Nitrogen in Landfill Leachate on Red Mud Modified by Sulfonation Coupling

Adsorption of COD and Ammonia Nitrogen in Landfill Leachate on Red Mud Modified by Sulfonation Coupling

Using polysodium p-styrene sulfonate and silane coupling agent (KH560) as modifiers, red mud was modified by sulfonation and coupling, and used in the adsorption treatment of landfill leachate. The effects of pH value, dosage of adsorbent, adsorption time and reaction temperature on the adsorption o...
