    摘要： Method for preparing a filtration membrane and a filtration membrane prepared by the method. According to one embodiment, the method involves casting a polymer solution onto a porous support to form a coated support. The coated support is then quenched to form a membrane/support composite, and the membrane/support composite is then dried. Next, a first end of a first piece of adhesive tape is applied to the membrane side of the composite, and the second end of the first piece of adhesive tape is applied to a first rotatable winder. In addition, a first end of a second piece of adhesive tape is applied to the support side of the composite, and the second end of the second piece of adhesive tape is applied to a second rotatable winder. The two winders are then rotated so as to pull apart the membrane from the support.

    摘要： A composite polyamide reverse osmosis membrane. The membrane includes a microporous support and a polyamide layer disposed over the microporous support, the polyamide layer including iodine atoms covalently bonded thereto. The membrane is preferably prepared by a process that includes the steps of providing a microporous support, forming a polyamide layer over the microporous support, and treating the polyamide layer with an aqueous solution comprising a compound, the compound comprising at least one iodine atom. Examples of the compound comprising at least one iodine atom include molecular iodine, iodine monobromide, iodine monochloride and iodine trichloride. The iodine-containing compound may be added to an aqueous solution and dissolved therein or may be formed in situ in the aqueous solution, for example, by adding to the aqueous solution an iodide salt and an oxidizing agent.

    摘要： A composite polyamide reverse osmosis membrane and method of producing same. In one embodiment, the membrane is made by coating a porous polysulfone support for about 40 seconds with an aqueous solution containing (i) a polyfunctional primary or secondary amine in the form of 1.6 wt. % of meta-phenylenediamine (MPD), (ii) a polyfunctional tertiary amine in the form of 0.4 wt. % N,N,N′,N′-tetramethyl-1,6-hexanediamine (TMHD), and (iii) a polar solvent in the form of 0.2 wt. % 2-ethyl-1,3-hexanediol (EHD). Next, the excess aqueous solution is removed, and the coated support is dipped for about 1 minute in a 0.1 wt. % organic solvent solution of trimesoyl chloride (TMC) in a mixture of alkanes having from 8 to 12 carbon atoms. After draining the organic solvent solution off, the resulting composite membrane is air dried at room temperature for about 1 minute and then rinsed in a 0.2% Na2CO3 aqueous solution for 30 minutes at room temperature. The resultant membrane exhibits a flux of 46.5 gfd and a salt rejection of 97.1% when used at 225 psi for an aqueous solution containing 2000 ppm of NaCl. In another embodiment, instead of including a polyfunctional tertiary amine in the aqueous solution, there is included the reaction product of a polyfunctional tertiary amine and a strong acid, preferably in a ratio ranging from greater than 1:0, respectively, to less than or equal to 1:(0.95)n, respectively, where n is the number of tertiary functional groups in the polyfunctional tertiary amine.

    摘要： A composite polyamide reverse osmosis membrane and method of producing same. In a preferred embodiment, the membrane is made by coating a porous polysulfone support with an aqueous solution containing 2 wt % m-phenylenediamine (MPD), and 0.1 wt % di(ethylene glycol) hexyl methyl ether. Next, the excess solution is removed, and the coated support is dipped in 0.1 wt % organic solvent solution of trimesoyl chloride (TMC) in a mixture of alkanes having from 8 to 12 carbon atoms. After draining the TMC solution off, the resulting composite membrane is air dried and then rinsed in a basic aqueous solution. The resultant membrane exhibits a flux of 21.3 gfd and a salt rejection of 98.9% when used at 225 psi for an aqueous solution containing 2000 ppm of NaCl.
