In the present study the Mediated Electrochemical Oxidation (MEO) process with cerium and nitric acid as the oxidizing medium was employed for the destruction of ethylenediaminetetraacetic acid (EDTA) in a continuous feeding mode. The control parameters in the process were the system temperature, concentration of nitric acid, cerium(IV) concentration, aqueous EDTA concentration, flow rate of EDTA addition, and feeding time. A new model was proposed for calculating the remaining organic in MEO solution during a continuous process of organic addition followed by destruction and hence CO2 produced. It showed a way for large organic destruction in a long time MEO process treatment. Experimental results confirmed that the modeling predictions were accurate. |
