摘要

This paper presents the study of the degradation of the pesticide atrazine, employing photoassisted electrochemical methods at a dimensionally stable anode of nominal composition Ti/Ru_(0.3)Ti_(0.7)O_2. All experiments were performed in a flow cell, and the effects of current density, electrolyte flow rate, as well the use of different supporting electrolytes are reported. The results indicate that the energy per order (E_(EO)/kW h m~(-3) order~(-1)) is substantially reduced when the photochemical and electrochemical techniques are combined. It is observed that complete atrazine removal is achieved at low current densities when the combined method is employed, thus reducing the energy required to operate the electrochemical system.
