The synergy of Fe and Mn as layered double hydroxides for electrochemical arsenic remediation

Key Points

• Electrochemical remediation of arsenic achieved significant efficiency with iron and manganese layered double hydroxides, enhancing environmental safety.
• A notable reduction in arsenic concentration was observed with a combined removal rate exceeding 90% in laboratory conditions.
• Assessment using layered double hydroxides shows a promising method for heavy metal removal from contaminated water sources.
• Further investigations are necessary to validate results across diverse environmental settings and scale up applications.
