Abstract:
A method of removing organic contaminants from contaminated liquid, gas, soil in fluid form, or mixtures thereof, comprising the steps of:(a) producing discrete non-clumping mechanically stable geometric shapes of a blend of an elastomeric material which includes at least one elastomer selected from the group consisting of polystyrene-butadiene copolymers, polystyrene-butadiene-polystyrene triblock copolymers, polystyrene-isoprene-polystyrene triblock copolymers, and polystyrene grafts of elastomers with about 5-45% by weight of a thermoplastic polymer which is a polystyrene, a polyolefin, or mixtures thereof; (b) providing the shapes in a loose form or packing; and (c) bringing a fluid containing organic contaminants into contact with the shapes in loose form or packing so that the shapes absorb organic contaminants from the fluid.
