Performance Efficiency of Electrocoagulation Adsorption Process of Oxyfluorfen Herbicide from Aqueous Solutions Using Different Anodes

In the last decades, the use of agrochemicals has been a common practice in intense agriculture, which has considerably increased pollution problems of surface and ground water. Oxyfluorfen [2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluromethyl)-benzene], a member of the herbicide class nitrodiphenyl ether, has a high degree of weed control and great versatility of application. Oxyfluorfen is considered to be highly resistant to degradation in water. And has Potential adverse effects on the ecosystemeven if present at very low concentration levels, where the half-life of oxyfluorfen ranged from 72 to 160 days for water. Many conventional methods have been successfully applied for the efficient removal of oxyfluorfen from water sources such as adsorption, advanced oxidation, photo Fenton, UV/H₂O₂ , and biological treatment. 

In recent years novel methods for water purification have been developed including chemical, electrochemical and photochemical processes. In this scenario, the electrocoagulation (EC) is an electrochemical has attracted increasing interest as a promising powerful method for efficiently removing pesticides from water such as Malathion, methyl parathion, atrazine and triazophos, imidacloprid and chlorpyrifos, and 2,4- dichlorophenoxyacetic Acid (2,4-D).The aim of this study is to conduct an experimental investigation on the removal of a oxyfluorfen and COD from the aqueous solution using the electrocoagulation method. and to investigate the kinetic and adsorption isotherm studies on the removal efficiency.(Read more)
