Electrochemical oxidation of two organophosphoric obsolete pesticide stocks

Organophosphoric pesticides are widely used for crop and fruit tree treatment, but their disposal causes serious environmental problems. Two commercial organophosphoric pesticides (Monocrotophos and Phosphamidon) were treated by an electrolysis system using Ti/Pt as anode and stainless steel 304 as...

Description
Summary:Organophosphoric pesticides are widely used for crop and fruit tree treatment, but their disposal causes serious environmental problems. Two commercial organophosphoric pesticides (Monocrotophos and Phosphamidon) were treated by an electrolysis system using Ti/Pt as anode and stainless steel 304 as cathode. A number of experiments were run in a laboratory scale pilot plant and the results are presented. For Monocrotophos, the achieved reduction was over 28%, while for Phosphamidon it was nearly 26%. Phosphamidon had a higher energy demand than Monocrotophos. The COD/BOD5 ratio was improved considerably after electrolysis for both pesticides examined. Therefore, electrochemical oxidation could be used as a pretreatment method for their detoxification. Copyright © 2005 Inderscience Enterprises Ltd.
