Arsenic is a chemical pollutant and cancer-causing agent that continues to be a global problem. Low-cost strategies are needed to treat arsenic-polluted water. In this study, investigators treated polluted water with either peanut shells or peanut shell biochar (charcoal) to test their efficiency for removing arsenic.

Key Findings

Key Findings: Peanut shell biochar removed 95% Arsenite and 99% Arsenate. Authors conclude that converting peanut shells into charcoal is a low-cost, sustainable, and efficient way to treat arsenic-rich water.
