Abstract
The invention discloses a preparation method of borax liquor. The preparation method comprises the following specific steps of: preparing electrophoresis buffer liquor; precisely weighing materials, and dissolving the materials by using the buffer liquor to obtain liquor with mass fraction not less than 50%; placing the liquor in a refrigerator for refrigerating for at least 12 hours, wherein the temperature of the refrigerator is 1 DEG C-2 DEG C; removing from the refrigerator, and then filtering by using a micro-porous membrane; placing the filtered precipitates into buffer liquor to carry out flushing, and then pouring into a capillary tube separating tube; centrifuging at a high speed for at least three minutes, cooling for one minute after getting out the precipitates, and centrifuging at the high speed for one minute again to obtain the borax liquor. Size of membrane holes for filtering of the micro-porous membrane is 0.2 mu m-0.3 mu m; an electronic layer becomes thinner with ion concentration migration, and stops becoming thinning when electroosmotic flow is descended to 3. The preparation method disclosed by the invention has beneficial effects of being stable in condition, simple to operate, very high in liquor sensitivity, basic in temperature, good in separating effect, less in interference and capable of preparing the borax liquor with a proper proportion according to needs.
Description
Technical field
The present invention relates to a kind of experimental technique, specifically, refer to the preparation method to borax soln.
Background technology
Borax is also tincal, is a kind of not only soft but also light colourless crystallization material.Borax has a lot of purposes, as we be familiar with as the glaze of sterilizing agent, antistaling and antiseptic agent, water-softening chemicals, eyewash, soap additive, pottery and frit etc., in industrial production, borax also has important effect.Be mainly used in glass and Enamel Industry.In glass, can strengthen transmission of ultraviolet rays, improve transparency and the resistance toheat of glass.In enamelware, can make enamel difficult drop-off and make it have gloss.At the welding compound of special optical glass, glass fibre, non-ferrous metal, the aspects such as the refining of the binding agent of jewelry, printing and dyeing, washing (silk and woolen knitwear etc.), gold, makeup, agricultural chemicals, fertilizer, borax soap, sanitas, frostproofer and medical use sterilizing agent be also widely used.Borax is the basic raw material of producing boron-containing compound, and nearly all can make through borax containing boride.They have important and purposes widely in the departments such as metallurgy, iron and steel, machinery, military project, cutter, papermaking, electron tube, chemical industry and weaving.Medically, borax is anticorrosion for the sterilization of skin mucosa, the treatment of skeletal fluorosis, tinea pedis, pulpitis, colpitis mycotica, cervical erosion, bedsore, acne, eczema of external auditory canal, dermopathic herpesvirus disease, epilepsy, for the treatment of tumour.In animal medicine, borax, for the treatment of chicken trachitis, goat infective pustule, porcine mycoplasmal pneumonia, the chronic mucus endometritis of ox, also enjoys people's concern as fodder additives.For weedicide, for noncrop area total weed control, except independent use, mixed with sodium chlorate, to lower the inflammableness of sodium chlorate.
Summary of the invention
For overcoming above-mentioned technical problem, we have proposed following technical scheme:
To the preparation method of borax soln, concrete steps are as follows:
Configuration electrophoresis buffered soln;
Precision takes raw material, then with damping fluid, it is dissolved, and obtains massfraction and is no less than 50 percent solution;
Be positioned in refrigerator and refrigerate, at least 12 hours time, the temperature of described refrigerator is 1-2 degree Celsius;
From refrigerator, remove, then with microporous membrane, filter;
Throw out after filtering is put into damping fluid and rinse, and then pour in kapillary separator tube;
High speed centrifugation, at least 3 minutes, cold putting one minute after taking out, high speed centrifugation is one minute again.
In the present invention, the fenestra that described microporous membrane filters, size is 0.2-0.3um.
In the present invention, described ionic concn is along with migrating, and electronic shell attenuation stops when electroosmotic flow reduces to 3.
The invention has the beneficial effects as follows, conditional stability, operating recommendation, solution sensitivity is very high, Ji Wendu, good separating effect, disturbs less, can configure as required the borax soln of proper ratio.
Embodiment
To the preparation method of borax soln, concrete steps are as follows:
Configuration electrophoresis buffered soln;
Precision takes raw material, then with damping fluid, it is dissolved, and obtains massfraction and is no less than 50 percent solution;
Be positioned in refrigerator and refrigerate, 12 hours time, the temperature of described refrigerator is 2 degrees Celsius;
From refrigerator, remove, then with microporous membrane, filter;
Throw out after filtering is put into damping fluid and rinse, and then pour in kapillary separator tube;
High speed centrifugation, 3 minutes, cold putting one minute after taking out, high speed centrifugation is one minute again.
The fenestra that described microporous membrane filters, size is 0.2um.
Described ionic concn is along with migrating, and electronic shell attenuation stops when electroosmotic flow reduces to 3.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
