Experimental assessment of electrochemical processes in the remediation of atrazine contaminated soils

摘要

The electrochemical oxidation of an atrazine solution obtained from a flushing treatment of a contaminated soil was investigated. The influence of ethanol on atrazine oxidation was studied. Results show that the electrogenerated Fenton's reagent provides a complete degradation of atrazine and its main chlorinated by-products via N-dehalky6lation and dechlorination. This process therefore presents an effective alternative to the chemical oxidation tretment which necessarily needs a further biological state.
