Comparative study for microcystin-LR sorption onto biochars produced from various plant- and animal-wastes at different pyrolysis temperatures: Influencing mechanisms of biochar properties

摘要

Highlights?Biochars produced from various materials at different temperatures were characterized.?Microcystin-LR sorption ability varied as a function of biochar structural properties.?At the same production temperature chicken manure biochars showed the best sorption.?High ash content might be important for enhancing microcystin-LR sorption by biochars.?Chicken manure biochars were the most efficient sorbents to remove microcystin-LR.AbstractDiverse biochars produced from various feedstock sources (i.e., plant- and animal-wastes) at different pyrolysis temperatures (PTs) were characterized for their structural properties and sorption behaviors of aqueous microcystin-LR (MC-LR). Results indicated that MC-LR sorption capability of tested biochars varied as a function of biochar structural properties. Sorption mecha
