Abstract
Disclosed is a method of removing hormone(s) from a liquid, the method comprising contacting the liquid with a filter comprising activated carbon fibers. Also disclosed is an article of manufacture comprising (i) a filter comprising activated carbon fibers and (ii) instructions informing a user that the filter is capable of removing hormone(s) from I.
Claims36
A method for removing hormone(s) from a liquid, the method comprising contacting the liquid with a filter comprising activated carbon fibers, said filter having a bulk density of from about 0.15 g/cm3 to about 0.8 g/cm3, and said activated carbon fibers having diameters of from about 5 μm to about 50 μm and fiber lengths of from about 10 μm to about 10 mm, wherein said activated carbon fibers have an inter-fiber spacing whereby the filter removes at least about 90% of the hormone(s) at a flow rate of 1 liter per minute with a total influent volume often liters at a hormone concentration of 100 nM.
A method for removing hormone(s) from a liquid, the method comprising contacting the liquid with a filter comprising activated carbon fibers, wherein said activated carbon fibers have an inter-fiber spacing whereby said filter has a bulk density of from about 0.15 g/cm3 to about 0.8 g/cm3, and said activated carbon fibers have diameters of from about 5 μm to about 50 μm and fiber lengths of from about 10 μm to about 10 mm.
A method for removing hormone(s) from a liquid, the method comprising contacting the liquid with a filter comprising activated carbon fibers, wherein said activated carbon fibers have an inter-fiber spacing whereby the filter removes at least about 90% of the hormone(s) at a hormone concentration of 100 nM and with said activated carbon fibers having a mass of from about 62 g to about 124 g.
A method for removing hormone(s) from a liquid, the method comprising contacting the liquid with a filter consisting essentially of activated carbon fibers, wherein said activated carbon fibers have an inter-fiber spacing whereby said filter has a bulk density of from about 0.15 g/cm3 to about 0.8 g/cm3, and said activated carbon fibers have diameters of from about 5 μm to about 50 μm and fiber lengths of from about 10 μm to about 10 mm.
