Methods
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
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.
