Chromium contamination poses a significant environmental concern due to its toxic effects and potential health risks. Traditional methods for removing chromium from contaminated sites often face efficiency challenges. However, electrokinetic remediation has emerged as a promising technique for various heavy metal remediation, including chromium. By applying an electric field, electrokinetics utilizes electrochemical processes like electromigration, electroosmosis, and electrophoresis to transport charged species, including chromium ions, towards the electrodes. This paper focuses on using electrokinetics for chromium removal and explores the integration of seaweed as a reactive permeable membrane in the electrokinetic setup for 0.25 to 1.25 V. Seaweed possesses unique properties such as high porosity, ion exchange capacity, and metal-binding capabilities, making it an attractive material to enhance the removal efficiency of chromium ions. The objective is to investigate the effectiveness of electrokinetics with seaweed as a reactive permeable membrane and assess the role of oxalic acid and sodium hydroxide as electrolytes. The result showed that the maximum efficiency was obtained for 1.25 V. This research aims to contribute to sustainable approaches for addressing chromium contamination, protecting both the environment and human health.
