Development of a novel and efficient biochar produced from pepper stem for effective ibuprofen removal.

A potential biochar from pepper stems (PS-biochar) was developed via a one-stage pyrolysis process of precursor at 700 °C and employed to adsorb ibuprofen (IBP) in water media. Results showed that PS-biochar was a carbonaceous mesoporous adsorbent with well-developed porosity (S = 727.5 m/g and V = 0.
