Activated Carbons for Arsenic Removal from Natural Waters and Wastewaters: A Review

The arsenic pollution of waters and wastewaters is concerning many countries across the world, and because of the effects of arsenic on human health, its removal from waters is of great importance. Adsorption using functionalized activated carbons as a technique for the removal of arsenic from water...

Adsorption using functionalized activated carbons as a technique for the removal of arsenic from water streams has gained great attention.

The review article concludes that most of the experimental data fit both Langmuir and Freundlich isotherms. In this review, the recyclability and reuse of the materials are also reported, and the findings show that for both arsenite and arsenate, even after several adsorption cycles, the material can be further used as an efficient adsorbent for arsenic removal.Elie MeezAthanasia K.
