Corn Cob Biochar Filters Pull Ammonia and Micro and Nanoplastics From Water
Researchers at the University of Delaware have converted discarded corn cobs into high‑performance biochar filters that simultaneously adsorb dissolved ammonia and micro‑/nanoplastic particles. In lab tests, the optimized 700 °C corn‑cob biochar (CCB700) removed about 64% of ammonia at 10 ppm and more than 97% of polystyrene particles ranging from 0.1 to 2 µm, without releasing detectable PAHs. The material can be regenerated and reused, retaining over half its ammonia‑removal capacity after three cycles. The approach links water purification with carbon‑rich waste valorization, offering a low‑cost, circular solution for rural and agricultural settings.
