碩士 === 弘光科技大學 === 環境工程研究所 === 101 === The main purpose of this study is to develop a novel electrochemical system containing electrocoagulation. we have developed the electrocoagulation system on treatment of salicylic acid wastewater. For treatment of salicylic acid, several parameters were evaluated to characterize the salicylic removal efficiency, such as various electrode pairs and applied voltage and temperatures. The effects of the applied voltage and temperature on the electrical energy consumption were also investigated. The optimum electrode pairs and applied voltage and temperature were found to be Al/Al and 20V and 308 K. Under these conditions, the salicylic acid concentration of aqueous salicylic acid solutions decreased by more than 90 %. The Adsorption Kinetics rate constants with pseudo-second-order models for salicylic acid removal at various applied voltages and temperature.
