Technical field
The present invention relates to a kind of method of membrane filtration material, specifically relate to the be coupled method of reinforced film filtration hyaluronic acid fermentation liquid of magnetization this physical technique and membrane separation technique.
Background technology
Hyaluronic acid (Hyaluronic Acid, HA) be the linear polymeric mucopolysaccharide that forms by the repeating unit that glucuronic acid and acetylglucosamine are constituted by β 1-3 and β 1-4 glycosidic link, in bovine vitreous body, found first by Meyer and Palmer in 1934.The length of its molecular chain and molecular weight heterogeneity, disaccharide units are 300～1100 pairs, molecular weight ranges 10
5～10
7Da.HA is water-soluble, is insoluble to organic solvents such as alcohol, ketone, ether.The aqueous solution is electronegative, shifts to negative pole during electrophoresis.Because its solution has superpower retentiveness, visco-elasticity and biological easily absorptivity, all have a wide range of applications in fields such as superior cosmetics, medical science, food and study.
Preparation hyaluronic acid commonly used at present mainly contains two kinds of approach: a kind of is to extract from animal tissues; A kind of is to extract from microbial fermentation solution.The Production by Microorganism Fermentation hyaluronic acid has solved the raw material sources problem for animal tissues's extraction method, and can obtain the HA of macromolecule, high yield.Remove in the fermented liquid and contain HA, also have materials such as protein and lactic acid.Usually adopt organic solvent such as CPC, ethanol, acetone etc. through repeatedly purify the HA finished product, as patent CN1195027, CN1597704 etc.The common operational path of this method is long, complicated, time-consuming, the cost height; Adopt more organic solvent, easily cause secondary pollution.Though membrane technique has application in the HA fermented liquid separates, generally all be as a kind of auxiliary separation means, be used for thalline or small molecular weight and remove, still need organic solvent to separate.As patent USA4517295, US4801539 etc., adopt MWCO 10 000, small-molecule substance is removed in 20 000,30 000Da ultra-filtration membrane diafiltrations.
The present invention is to realize that membrane technique is an agent technology, and separating the HA fermented liquid is ultimate aim.Yet unavoidably have membrane pollution problem in the membrane filtration HA fermented liquid process, this is a most important reason that hinders application of membrane.Film pollute to shorten film work-ing life, makes people form the consciousness of a kind of " the film cost is too high " for a long time, and this has influenced the popularization and the application of membrane technique greatly.Therefore, take the efficient hardening measure to alleviate film and pollute, improving membrane sepn efficient is the key of application of membrane.
Magnetization technology is a kind of technology of material being carried out magnetic field treatment, and this technology all is widely used in that chemical industry, environment, medical science, water treatment etc. are multi-field.Because magnetic field is an energy field, magnetization exerts an influence to many physicochemical property of handled solution system.Can reduce the surface tension and the solid surface potential energy of solution as the effect in magnetic field, thereby the adsorption layer that causes solid surface thickens; Magnetization can also reduce the viscosity of solution, makes it be easier to carry and next step processing.Magnetic field also exerts an influence to pH, specific conductivity, the specific inductivity of solution in addition.The effect of magnetic field treatment and magneticstrength, magnetizing time, solution are relevant in the chemical property of the flow velocity of field regions, magnetization water temperature, solution etc.That magnetization technology has is easy for operation, less investment, low, simple and easy to do, nontoxic, the non-secondary pollution of working cost, saves human and material resources, and advantages such as save energy are very promising technology.
Magnetization technology is applied to membrane filtration HA fermented liquid process, utilizes magnetic field to the physical chemistry influence that filtration procedure produces, and will produce some and help filtering effect a bit, and the reinforced film strainability reduces film and pollutes.
