KOH-Activated Iron-Modified Corn Straw Biochar for Nitrate Removal: Preparation, Adsorption Performance, and Mechanism

Nitrate contamination of groundwater requires low-cost adsorbents with strong affinity for anionic species. This study developed an iron-modified corn straw biochar (Fe-BC) by coupling KOH activation with FeCl3 impregnation and secondary pyrolysis, thereby integrating a porous ca...
