Iron-Modified Composite Adsorbent Coating For Acid Red 1 Removal And Its Regeneration Feasibility By Heterogeneous Fenton-Like Process

Adsorption is widely used technique in wastewater treatment because the process is low cost, ease of operation and efficient. However, regeneration of spent adsorbents is usually restricted by the strong interactions between the surface of adsorbents and adsorbates. It would be very economical if t...
