The invention relates to particulate sorbents such as sorbents that can be used for mercury removal applications. The sorbent may comprise at least one ammonium phosphate and at least one active carbon chosen from non-halogenated active carbon and halogenated activated carbon, the halogenated activated carbon containing at least one halogenated impregnating agent on its surface. Methods of making sorbents and methods of removing mercury from, for example, combustion gases generated by burning coal are also provided. |
