Abstract

This paper studies the degradation of herbicide atrazine. It was degraded by three-dimension-electrode electrochemical oxidation, which platinum was used as cathode and anode, and activated carbon was used as packed material and adsorbent. The effect of input current, initial pH, electrolyte concentration and solution temperature on degradation efficiency of atrazine was discussed. The results showed that atrazine can be effectively degraded by three-dimension-electrode electrochemical oxidation. The optimal conditions of operation are as follows: input current is 30mA, initial pH is 4, solution temperature is 20°C, and electrolyte concentrations is 0.10mol/L. Under the optimal conditions, degradation efficiency of atrazine can reach more than 99%, and the degradation rate is highest.
