A method and product for removing nitrogen compound molecules from gasoline or diesel fuel includes exposing the gasoline or diesel fuel to a plurality of molecularly imprinted polymer beads (MIPS) that have receptor sites on the surfaces thereof that include imprints that match the physical shape of at least a portion of a nitrogen compound molecule. A quantity of the nitrogen molecules align with and adhere to some of the receptor sites and, accordingly, they are removed from the gasoline or diesel fuel producing a remediated or sweetened gasoline or diesel fuel. According to one embodiment, the MIPS are contained in an enclosure having a plurality of openings large enough to permit the solution to pass through and small enough so as to prevent the MIPS from passing through. According to another embodiment the MIPS are applied (i.e., coated) to the inside surface of a conduit and the gasoline or diesel fuel is forced or allowed to flow through the conduit thereby removing some of the nitrogen molecules therefrom. The MIPS are treated after use to remove a sufficient quantity of the nitrogen molecules from the receptor sites and are reused.

A method and product for removing sulfur compound molecules from gasoline or diesel fuel includes exposing the gasoline or diesel fuel to a plurality of molecularly imprinted polymer beads (MIPS) that have receptor sites on the surfaces thereof that include imprints that match the physical shape of at least a portion of a sulfur compound molecule. A quantity of the sulfur molecules align with and adhere to some of the receptor sites and, accordingly, they are removed from the gasoline or diesel fuel producing a remediated or sweetened gasoline or diesel fuel. According to one embodiment, the MIPS are contained in an enclosure having a plurality of openings large enough to permit the solution to pass through and small enough so as to prevent the MIPS from passing through. According to another embodiment the MIPS are applied (i.e., coated) to the inside surface of a conduit and the gasoline or diesel fuel is forced or allowed to flow through the conduit thereby removing some of the sulfur molecules therefrom. The MIPS are treated after use to remove a sufficient quantity of the sulfur molecules from the receptor sites and are reused.

A method and product for removing at MTBE molecules from a solution, such as a contaminated aquifer, includes exposing the solution to a plurality of molecularly imprinted polymer beads (MIPS) that have receptor sites on the surfaces thereof that include imprints that match the physical shape of at least a portion of an MTBE molecule. A quantity of the MTBE molecules align with and adhere to some of the receptor sites and, accordingly, they are removed from the solution producing a remediated solution. According to one embodiment, the MIPS are contained in an enclosure having a plurality of openings large enough to permit the solution to pass through and small enough so as to prevent the MIPS from passing through. According to a preferred embodiment the MIPS are applied (i.e., coated) to the inside surface of a conduit and the solution is forced or allowed to flow through the conduit thereby removing some of the MTBE molecules therefrom.

A method and product for decaffeinating an aqueous solution, such as a cup of coffee or tea, includes exposing the aqueous solution (that is to be decaffeinated) to a plurality of molecularly imprinted polymer beads (MIPS) that have receptor sites on the surfaces thereof that include imprints that match the physical shape of at least a portion of a caffeine molecule. A quantity of the caffeine molecules align with and adhere to some of the receptor sites and, accordingly, they are removed from the aqueous solution producing a decaffeinated aqueous solution. The MIPS are contained in an enclosure having a plurality of openings large enough to permit the aqueous solution to pass through and small enough so as to prevent the MIPS from passing through. Accordingly, the MIPS are absent from the decaffeinated aqueous solution. A variety of ways of affecting the efficacy of the process are described, such as varying the time the aqueous solution is exposed to the MIPS or varying the quantity of MIPS (beads) that the aqueous solution is exposed to. Processes useful for creating the MIPS and of removing the caffeine molecules therefrom (i.e., cleaning the MIPS so that they are suitable to use in decaffeinating the aqueous solution) are described. The cleaning and subsequent reuse of the MIPS is also described.
