- Abstract
With the developments in treatment technologies, including porous materials in electrochemical systems have recently become the focus of researchers' attention. In electrochemical methods, operating cost is as important as efficiency. It is possible to increase the system performance by increasing the effective electrode surface by incorporating activated carbon, which can be produced from biomass, into electrochemical oxidation systems. This study investigated using activated carbon from walnut shells as a microelectrode in the electrochemical oxidative degradation of malachite green. When potential differences between 2V and 4V are applied to 2DES and 3DES reactors containing MG solution, a higher % MG Removal was obtained in 3DES reactors than in 2DES reactors. When the potential difference is 4V, a value of 0.026 (min-1 ) k1.3D and 0.0117 (min-1 ) k1.2D are obtained. In 3DES reactors, the rate constant at 0.003 A/cm² was achieved as 0.0167 (min-1 ) k1.3D, while at 0.010 A/cm², it increased by approximately 5 times, reaching a value of 0.0845 min-1 k1.3D. Similarly, in 3DES reactors, when the current density increased from 0.003 A/cm² to 0.010 A/cm², the mass transfer rate increased from 0.011 (cm/s) to 0.05633 (cm/s).
