摘要： The present invention relates in part to a lignin composition and a method of fabricating a lignin composition. The invention also relates in part to a method of using a lignin composition to adsorb onto a petrochemical oil comprising the steps of providing a solution of lignin in an alcohol, providing an oil on a liquid surface, contacting the oil with the solution of lignin in an alcohol, adsorbing the lignin to the oil, and removing the adsorbed oil from the surface of the liquid.

摘要： Construction for absorbing a fluid, for example, a liquid or gaseous, organic chemical, has an extended web, fabric, yarn or foam member and associated with the extended web, fabric, yarn or foam member is a water-insoluble polymer. The water-insoluble polymer can absorb the fluid organic chemical, and the construction provides for contact of the water-insoluble polymer with the fluid organic chemical when deployed in an environment where the fluid organic chemical may be present for absorption. The construction may be employed in aquatic, aqueous, or dry environments, as a blotter, a wipe or sponge, a filter, in a cartridge, and so forth.

摘要： Chemical-based methods and products for mitigating the impact of an oil spill are disclosed. The products act by herding, thickening, gelling, and reducing adhesiveness. N-fatty acid amino acid (FA-AA) conjugates display oil-herding behavior when formulated as a free acid in water-miscible organic solvents. A water-miscible organic solvent is not required if the FA-AA conjugate is formulated as a salt. Various salts of FA-AA conjugates are water soluble and can herd oils and increase the thickness of the oil layer. Replacement of the acid group of fatty acid α-amino acid conjugates with other groups that act as hydrogen bond donors and acceptors results in potent phase selective organo-gellants. The oil spill herders can be prepared from bio-based feedstocks and are biodegradable. The oil thickeners or gellants, which are prepared from bio-based feedstocks, have low toxicity, high capacity for oil and reduce the need to use an organic solvent to apply the thickener or gellant to the oil and water mixture in order to gel the oil phase. Formulae (IB), (II), (III)

摘要： A collection kit for the removal of unwanted material from a surface, said kit comprising: iv) ferromagnetic material to absorb and/or adsorb the unwanted material when spread across the unwanted material creating an area of operation; v) an apparatus having a magnetic source operable to attract the ferromagnetic material together with absorbed and/or adsorbed unwanted material when the magnetic source is touching or in the vicinity of the area of operation; and vi) means to dislodge the ferromagnetic material and absorbed and/or adsorbed unwanted material from the apparatus once the ferromagnetic material has been removed from the area of operation.
