Biochar impregnation with fe
WebFeb 24, 2024 · Ruan et al. prepared α-Fe 2 O 3 nanoparticles dispersed over biochar coated bentonite by the anaerobic 400 °C pyrolysis of rosin in the presence of Fe 3+-impregnated bentonite. The biochar coating improved the α-Fe 2 O 3 dispersion, resulting in a 95% removal efficiency for Cr(VI) within 1 min, and a maximum adsorption capacity … WebCorn stover biochar (CSB) and maple biochar (MB) were added into anaerobic digesters and evaluated for hydrogen sulfide (H 2 S) reductions. This was the first study to show Fe-impregnated biochar can eliminate H 2 S production. The novel study evaluated biochar addition on H 2 S reduction and nutrient concentrations using three experiments to test …
