Abstract
An effective treatment process for 2,4-dichlorophenol (2,4-DCP) in wastewater is highly essential, since it may cause great threat to our environment. In such context, a low-cost potential and environment-friendly technique has been demonstrated for the removal of a toxic compound 2,4-DCP from aqueous media. The electrochemically generated aluminum sorbent was used to remove 2,4-DCP from waste water by in-situ electrocoagulation and by adsorption. The experimental findings were analyzed based on the percent removal of 2,4-DCP with time. DCP-containing wastewater was electrocoagulated in a two-electrode monopolar electrocoagulation cell with aluminum as the sacrificial anode and 0.05 M NaCl as the internal electrolyte, with the electrolyte concentration kept constant throughout the experiment. Starting concentration and pH were found to have a significant impact on the electrocoagulation process for removing 2,4-DCP from wastewater.
