Abstract
The invention discloses a purifying disposing method of bacteria and organism in the multi-oxygen water, which comprises the following steps: irradiating through ultraviolet; filtering through filter membrane; distilling to remove impurity. The method guarantees the abundance of multi-oxygen (18O) in the disposing course, which reduces organic carbon content in the multi-oxygen water.
Description
Technical field
The present invention relates to a kind of UV-light of utilizing and obtain organism and the low tracer agent-heavy oxygen water (H of bacteria content
2 18O) purification process technique method.
Background technology
The oxygen element of occurring in nature has three kinds of stable isotopes, and its total mass number is respectively 16,17,18, and its abundance in natural water is respectively 99.76%, 0.04%, 0.2% atom.Wherein
16O is the ordinary oxygen element,
18O,
17The O oxygen element of attaching most importance to.
Heavy oxygen water (H
2 18O) be heavy oxygen (
18O) isotopic hydride has and ortho-water (H
2 16O) identical physicochemical property, but heavy oxygen (
18O) element can be used as tracer element, makes heavy oxygen water (H
2 18O) can be used as a kind of tracer agent and be widely used in fields such as nuclear medicine image, medicine, biological medicine, environment, chemistry, life science.
Heavy oxygen water (H
2 18O) be Positron Emission Computed Tomography (Positron Emission ComputedTomography, PET) the essential positron imaging medicine of technology
18Unique preparation raw material of F-FDG.The heavy oxygen of heavy oxygen water (
18O) abundance, ionic concn, total organic matter and bacteria content will directly influence the positron imaging medicine
18The synthetic yield of F-FDG.
Total organic content in the heavy oxygen water is weighed with total organic carbon (TOC) content, therefore usually, in heavy oxygen water purification treatment process, effectively reduce the content of ionic concn, total organic matter and bacterium, guarantee the TOC index in the heavy oxygen water, avoid heavy oxygen in the purification process process (
18O) reduction of abundance guarantees heavy oxygen aquatic product quality and range of application, and is very important for the purification process technique of heavy oxygen fishery products.
At present,, the patent of invention of the aquatic product technology of heavy oxygen of Shanghai Chemical Research Inst is only arranged, do not see the open report (periodical, patent etc.) of relevant heavy oxygen water treatment technology at home because the heavy oxygen fishery products still are a kind of product innovation at home.
Usually we can adopt the adding medicament: as hypochlorous acid, methods such as feeding ozone are carried out the sterilization of water, but these methods can increase the ionic concn of heavy oxygen fishery products and cause the last handling process difficulty, or introduce
16O atom and cause exchange, the fractionation of oxygen isotope, obviously reduce the heavy oxygen fishery products heavy oxygen (
18O) abundance.
Summary of the invention
Purpose of the present invention is exactly to provide bacterium and organic purifying treatment method in a kind of removal heavy oxygen water for the defective that overcomes above-mentioned prior art existence, this method is being utilized UV-light effectively to kill the bacterium of heavy oxygen water and is being reduced the organic while, can avoid heavy oxygen (
18O) reduction of abundance.
Purpose of the present invention can be achieved through the following technical solutions: bacterium in a kind of removal heavy oxygen water
With organic purifying treatment method, it is characterized in that this method comprises following processing step:
(1) UV-irradiation
The method direct irradiation of employing ultraviolet oxidation is removed bacterium and the organism in the heavy oxygen water;
(2) membrane filtration
Adopt millipore filtration that the heavy oxygen water after UV-irradiation is filtered;
(3) distillation removal of impurities
Adopt water distilling apparatus to distilling removal of impurities through filtering heavy oxygen water, obtain a kind of purified,
Can avoid heavy oxygen (
18O) the heavy oxygen water (H of abundance reduction
2 18O).
The wavelength region of described UV-light is 100 nanometers～420 nanometers.
Described UV-light is the UV-light of a certain specific wavelength, as wavelength 185 nanometers, or is two kinds simultaneously, as wavelength 185 nanometers and 254 nanometers, or is the UV-light of two or more wavelength simultaneously, as wavelength 185 nanometers, 254 nanometers and 270 nanometers.
The residence time of heavy oxygen water under UV-irradiation is more than 10 minutes in the described step (1).
The millipore filtration that adopts in the described step (2) is selected from poly(vinylidene fluoride) (PVDF) millipore filtration, perhaps polytetrafluoroethylene (PTFE) millipore filtration
The aperture of described millipore filtration is 0.22～0.5 micron.
The water distilling apparatus that adopts in the described step (3) is Rotary Evaporators or distilled water generator.
Still-process in the described step (3) is at high purity argon (Ar) or nitrogen (N
2) as distilling under the condition of protecting gas.
Described heavy oxygen water (H
2 18Heavy oxygen O) (
18O) abundance is 9.0%～99.9%.
The present invention adopts the method for UV-irradiation, kills most bacteriums and can interrupt most of chemical bond abilities in the organism because UV-light has, so can utilize UV-irradiation to kill bacterium in the heavy oxygen water, decomposes residual organic in the heavy oxygen water.
Bacterium and residual organic matter are under the effect of UV-light in the heavy oxygen water, and bacterium is killed and becomes corpse, and residual organic matter is decomposed into charged small organic molecule, not charged small organic molecule and oxidized generation carbonic acid gas.Because adopt the mode of UV-irradiation, in this process, heavy oxygen water can not contact other oxygen carrier, can not cause heavy oxygen (
18O) reduction of heavy oxygen abundance in the treating processes can be effectively avoided in the variation of abundance in kill bacteria and organic while of reduction.In heavy oxygen water purification treatment process, after utilizing ultraviolet light sterilization and decomposing, also need to utilize other purifying method, place to go ion, bacterium corpse and small organic molecule that is decomposed and carbonic acid gas.
In heavy oxygen water purification treatment process, after utilizing ultraviolet light sterilization and decomposing organic matter, can settle membrane filtration, simple distillation technology, in order to remove the bacterium corpse, remove the not charged organism of ion, small molecules, charged organism and carbonic acid gas, finish whole heavy oxygen water purification treatment process.
The present invention utilizes existing membrane filtration technology, and promptly adopting the aperture is 0.22～0.5 micron filter membrane.It is placed in heavy oxygen water through after the UV-light purifying treatment, can effectively filters and remove through the bacterium corpse in the heavy oxygen water after the UV-light purifying treatment, chip etc.
The present invention utilizes existing laboratory distillation technique again, promptly utilize simple water distilling apparatus (as laboratory Rotary Evaporators commonly used, distilled water generator etc.) that heavy oxygen water is distilled, in order to remove ion, the not charged organism of small molecules, charged organism and carbonic acid gas etc., in still-process, to note to make heavy oxygen water ingress of air, should adopt high purity argon (Ar) or nitrogen (N
2) as the protection gas distill, avoid airborne oxygen to heavy oxygen (
18O) isotopic fractionation, the heavy oxygen of reduction heavy oxygen water (
18O) abundance.
