AMOchar: Amorphous manganese oxide coating of biochar improves its efficiency at removing metal(loid)s from aqueous solutions

Popis výsledku v původním jazyce

A novel sorbent made frombiochar modifiedwith an amorphous Mn oxide (AMOchar) was comparedwith pure biochar, pure AMO,AMO+biochar mixtures and biochar+birnessite composite for the removal of variousmetal( loid)s from aqueous solutions using adsorption and solid-state analyses. In comparison with the pristine biochar, both Mn oxide-biochar composites were able to remove significantly greater quantities of various metal(loid)s from the aqueous solutions, especially at a ratio 2:1 (AMO:biochar). The AMOchar proved most efficient, removing almost 99, 91 and 51% of Pb, As and Cd, respectively. Additionally, AMOchar and AMO+biochar mixture exhibited reduced Mn leaching, compared to pure AMO. Therefore, it is concluded that the synthesis of AMO and biochar is able to produce a double acting sorbent (dorbent) of enhanced efficiency, compared with the individual deployment of their component materials.
