Abstract Details

2006, MS, University of Cincinnati, Engineering : Environmental Engineering.
In this study, an electrochemical reactor was used to investigate the degradation of 4-chlorophenol at neutral pH for studying the impact of three key parameters (initial concentration, ionic strength, and applied current) on the destruction process. A cathodic reduction of 4-chlorophenol was not practical because water splitting was the dominant reaction mechanism. Anodic oxidation of 4-chlorophenol was then investigated. The applied current ranged from 50mA to 350mA (14.75mA/cm 2to 103.24mA/cm 2), four initial concentrations (25ppm, 50ppm, 100ppm, and 200ppm), and three ionic strengths (0.5M, 1.0M, and 1.5M) were studied. Two oxidation modes, direct and combined (direct plus indirect) oxidation, were studied. Na 2SO 4was used as electrolyte in direct oxidation, and NaCl was used in combined oxidation. Direct oxidation was found to follow saturation reaction model, while combined oxidation followed Pseudo first order kinetics. For combined oxidation, the reaction rate constant increased with applied current up to 300mA (88.5mA/cm 2) and then started to drop afterward. Over 99% removal of 4-chlorophenol within 6hrs in combined oxidation and was much faster and effective than direct oxidation.
