Abstract
Methods for the manufacture of sorbent compositions, sorbent compositions and methods for using the sorbent compositions. The methods include the utilization of an acidic halogen solution as a source of a halogen species that is dispersed on a solid sorbent. The use of the acidic halogen solution results in a highly active halogen species that demonstrates improved efficacy for the removal of heavy metal(s) from a flue gas. The sorbent composition includes a substantially amorphous halogen species associated with a solid sorbent such as powdered activated carbon (PAC).
