The Influence of Potential on the Performance of Aluminum-Aluminum (Al-Al) Electrodes Based on Microplastic Removal Efficiency and Turbidity Level

Abstract:

This research aims to investigate the potential effect on the performance of Al-Al electrodes in the electrocoagulation method. The influence of this potential can be observed through microplastic removal and turbidity levels. The research was conducted in situ using a chemical beaker, employing Al-Al electrodes at various different potentials (5, 10, 15, and 20 V) that were systematically investigated. The results of this research indicate that an increase in potential has a positive impact on the efficiency of microplastic removal and turbidity levels. Efficiency removal of microplastic and turbidity levels increase with an increase in potential until optimum condition. The microplastic removal efficiency was found to be 100% ± 0 at a potential of 10 V after 60 minutes of electrolysis, with a plate spacing of 2.5 cm and an electrolyte concentration of 0.01 mol/L. At a potential of 10 V, the value of NTU changed from >200 NTU to 30 NTU. This research showed that the effectiveness of the Al-Al electrodes performance is influenced by the potential.
