A method, comprising:
- contacting a feed stream comprising a physiologically active target material other than nitrate, iodine, selenium, and bis(2-ethylhexyl)phthalate selected from the group consisting of prescription drug, over-the-counter therapeutic drug, veterinary drug, fragrance, cosmetic, sunscreen agent, diagnostic agent, nutraceutical, biopharmaceutical active compound, growth enhancing chemical, antimicrobial, estrogenic steroid, antidepressant, selective serotonin reuptake inhibitor, calcium-channel blocker, antiepileptic drug, phenytoin, valproate, carbamazepine, multi-drug transporter, efflux pump, musk aroma chemical, triclosan, genotoxic drug, and mixtures thereof with at least one of a soluble and insoluble rare earth fixing agent to substantially reduce physiologically active target material in the feed stream.
A method, comprising:
- contacting a physiologically active compound-containing stream with at least one of an insoluble and soluble rare earth fixing agent to form an insoluble target material-containing fixing agent comprising at least a portion of the physiologically active target material and the rare earth, wherein the physiologically active compound is other than nitrate, iodine, selenium, and bis(2-ethylhexyl)phthalate wherein the physiologically active compound is selected from the group consisting of prescription drug, over-the-counter therapeutic drug, veterinary drug, fragrance, cosmetic, sun-screen agent, diagnostic agent, nutraceutical, biopharmaceutical active compound, growth enhancing chemical, antimicrobial, estrogenic steroid, antidepressant, selective serotonin reuptake inhibitor, calcium-channel blocker, antiepileptic drug, phenytoin, valproate, carbamazepine, multi-drug transporter, efflux pump, musk aroma chemical, triclosan, genotoxic drug, and mixtures thereof.
