Remarkable effect of the incorporation of titanium on the catalytic activity and SO2 poisoning resistance of magnetic Mn-Fe spinel for elemental mercury capture

▶ Hg0 capture by Mn-Fe spinel can be promoted by the incorporation of Ti. ▶ Ti in Mn-Fe spinel can improve its SO2 poisoning resistance. ▶ Fe-Ti-Mn spinel can be magnetically separated from the fly ash.
