A sorbent composition for the sequestration of mercury from a gas stream, a method for sequestering mercury from a gas stream and a method for the manufacture of a sorbent composition. The sorbent composition includes a highly porous particulate sorbent and at least two additive components, namely a non-halogen metal compound comprising a metal cation and an inorganic sulfur-containing compound, where at least a portion of the sulfur in the sulfur-containing compound has an oxidation state of equal to or less than +4. The method includes injecting the highly porous particulate sorbent and the two additive components into a gas stream, either discretely or as a single sorbent composition, to sequester mercury in the particulate sorbent. The method has a high degree of efficacy for mercury removal without requiring the addition of halogens to the gas stream.

A medium for fast, selective oil-water separation and/or oil absorption includes steel wool modified with a polymer a polymer or a polymer mixture. The polymer or the polymer mixture is adapted such that the medium is a superwetting material that is superhydrophobic and superoleophilic under water. The polymer or the polymer mixture includes polydimethylsiloxane, polytetrafluoroethylene, polyvinylpyrrolidone, or a combination thereof. The solution immersion method used to synthesize the medium requires only a single, simple step and affordable materials and, as a result, is easy to scale up.
