Claim 0:
1. A magnetic adsorbent for the capture of mercury from flue gas of coal combustion devices, said magnetic absorbent, comprising:
an activated carbon adsorbent;
an iron oxide forming a magnetic portion wherein magnetic activity of the magnetic portion is not blocked by the activated carbon, said magnetic portion being implanted on a surface of the activated carbon;
an additive including a photocatalyst and a halogen;
a binder;
a first additional additive including one or more of the group consisting of a magnetic sorbent, magnetic particles, and a magnetic catalyst;
wherein said iron oxide and said additive are implanted onto a surface of the adsorbent;
wherein said halogen enhances oxidation of the mercury in a contaminated stream of the flue gas when said magnetic adsorbent is placed into contact with said contaminated stream; and
wherein said iron oxide oxidizes mercury from elemental mercury (Hg) to Mercury Oxide (Hg II).
