Abstract
Wastewater treatment systems have great importance in dealing with increasing environmental pollution. In this study, a specially designed and constructed flow-through electrochemical cell was used to enhance the electrosorptive removal capacity of 2,4-Dichlorofenoxyacetic acid (2,4-D) pesticide from aqueous solutions onto high area activated carbon cloth (ACC) fixed-bed electrodes. The change in concentration of 2,4-D during the electrosorption process was followed by an online UV-Vis spectrophotometric system. Effects of operational parameters such as volumetric flow rate, applied potential and existence of Na2SO4 salt on electrosorption of 2,4-D were examined. Optimum values were found to be 10 mL·min-1 for volumetric flow rate and +900 mV for the applied potential to polarize ACC. Maximum capacity of 729 mg·gACC-1 has been achieved for removal of 2,4-D pesticides.
Highlights
Releasing various organic and inorganic pollutants into the ecosystems has been exponentially increased during the past several decades due to growing social civilization, industrialization and technology (Ghodbane et al ; Michalski & Ficek )
Activated carbon cloth (ACC), one of such quasi-three-dimensional adsorbent materials, has the additional advantage of mechanical integrity so that it can be designed as a stable electrode to carry out electrosorption processes for the removal of pollutants from wastewaters (Ania & Béguin ; Bayram & Ayranci ; Gineys et al )
À900 mV potential was applied to the saturated ACC electrodes while fresh 0.01 M Na2SO4 solution was cycling with volumetric flow rate of 10 mL·minÀ1 in the system and scanning-kinetic spectra were recorded in 2 min intervals
Summary
Releasing various organic and inorganic pollutants into the ecosystems has been exponentially increased during the past several decades due to growing social civilization, industrialization and technology (Ghodbane et al ; Michalski & Ficek ). Activated carbon cloth (ACC), one of such quasi-three-dimensional adsorbent materials, has the additional advantage of mechanical integrity so that it can be designed as a stable electrode to carry out electrosorption processes for the removal of pollutants from wastewaters (Ania & Béguin ; Bayram & Ayranci ; Gineys et al ).
