Atrazine removal using adsorption and electrochemical regeneration

This paper demonstrates the removal of atrazine using a novel carbon-based adsorbent to below 1.0 mug l(-1) and its subsequent electrochemical regeneration in a simple electrochemical cell. Effective electrochemical regeneration can be achieved with a treatment time as low as 20 min over a number of adsorption/regeneration cycles using laboratory prepared solutions. The results suggest that electrochemical modification of the particulate surface on electrochemical regeneration can result in adsorptive capacities three times greater than originally achieved.
