6(OH)
2, be the widely used biological active ceramic material of a class.Because its composition is similar to the inorganic components of living organism bone, thus cause the extensive concern of people.Along with improving constantly of people's understanding, many results of study show, hydroxyapatite be a kind of nontoxic, without carcinogenic, have no side effect and there is the biological active materials of good biocompatibility, the growth of bootable new bone after implanting; People also find that hydroxyapatite has solid alkali performance and stronger ion-exchange capacity, therefore obtain use widely in catalytic carrier, ion-exchange field; Poisonous ion can also be adsorbed simultaneously and there is temperature sensitive, humidity effect.In addition, recent studies have found that, the growth of nanometer hydroxyapatite energy anticancer, is free from side effects to normal cell, for preparation new generation anti-cancer medicament provides new approach.
Hydroxyapatite has much excellent characteristic, except with self character mutually outside the Pass, also have close relationship with its preparation method and microtexture.
The synthetic method of hydroxyapatite is roughly divided into two classes: Dry synthesis and Moist chemical synthesis.Dry method comprises mechanochemical synthesis and microwave fixes synthesis method; Moist chemical synthesis comprises hydrothermal synthesis method, the precipitator method, microemulsion method and sol-gel method etc.The pattern of hydroxyapatite has needle-like, spherical, bar-shaped, sheet etc.
At present, hydroxyapatite monocrystalline is mainly prepared by hydrothermal method, Wang Youfa etc. (silicate circulate a notice of, 2001,2,30-34) with four water-calcium nitrate and DAP for needle-like hydroxyapatite monocrystalline prepared by raw material; Chinese invention (application number 201110116542.1) reports one and has fluorescently-labeled fluoridated hydroxyapatite nanometer monocrystalline shuttle and preparation method thereof, is prepared have fluorescently-labeled nanometer monocrystalline shuttle by doped with rare-earth elements europium and terbium in fluoridated hydroxyapatite preparation process; Chinese invention (application number 201110116552.5) reports the method preparing rare earth doped fluorine hydroxyapatite monocrystal nanowire by hydrothermal method; Liu Huijuan etc., to adopt mechanical attrition method, make ball-milling medium with ethanol, and successfully synthesis has the hydroxyapatite nano sheet of crystalline orientation; Yuxiu Sun etc. (
ceram. Int, 2006,32,951-954) and be that raw material has prepared Hydroxyapatite mono-crystal nano-rod by reverse microemulsion process with polyoxyethylene glycol, cetyl trimethylammonium bromide (CTAB), normal hexane, propyl carbinol, hexanaphthene, four water-calcium nitrate and DAP.
The deficiency that the hydroxyapatite monocrystalline utilizing above-mentioned technology to prepare exists is: hydroxyapatite single crystal particle irregular arrangement, cannot form specific pattern, and specific surface area is less.
Summary of the invention
The object of the present invention is to provide a kind of preparation method taking plant as Template preparation and can form the Hydroxyapatite mono-crystal nano-rod of the special microtexture of plant, with soluble phosphate and calcium salt for raw material, water heat transfer is adopted to go out the Hydroxyapatite mono-crystal nano-rod that can form the special microtexture of plant.It is simple that the method has reaction system, and raw material is easy to get, easy to operate, the advantages such as environmentally safe.
For achieving the above object, the technical solution used in the present invention step is as follows:
(1) soluble phosphate is dissolved in deionized water, stirring make it dissolve completely transparent and homogeneous solution, and add plant template wherein, wherein dissolve 0.01-0.5 mole of phosphoric acid salt in often liter of deionized water, in often liter of phosphate solution, add 0.5-15g plant template;
(2) calcium salt of certain mass is added dropwise in above-mentioned aqueous phosphatic while stirring, drip rear continuation and stir 0.1-1h, then ultrasonic 5-10 minute, wherein the mol ratio of Ca:P is 1.67, solution ph is 8-12(sodium hydroxide, potassium hydroxide or ammoniacal liquor adjust ph), the speed of stirring is 200-800rpm;
(3) solution of step (2) is proceeded in hydrothermal synthesis reaction still, at 85-200 DEG C after constant temperature process 10-24h, then naturally cool to room temperature;
(4) solution of filtration step (3) gained, collect filter residue, filter residue ultrapure water supersound washing 15 minutes, then in the baking oven of 65 DEG C dry 12 hours, finally dried sample is put into retort furnace to calcine, namely obtain the Hydroxyapatite mono-crystal nano-rod that can form the special microtexture of plant.
Soluble phosphate described in the present invention be phosphoric acid normal salt or/and the acid salt of phosphoric acid, both mixing be arbitrary proportion mixing.
The normal salt of phosphoric acid described in the present invention be sodium phosphate or/and potassiumphosphate, both mixing be arbitrary proportion mixing; The acid salt of phosphoric acid be in disodium-hydrogen, potassium phosphate,monobasic, potassium primary phosphate, Secondary ammonium phosphate one or more arbitrarily than mixture.
The template of plant described in the present invention is the dried plant with macrofiber or dimension pipe.
The template of plant described in the present invention is a kind of in cotton, Herba Eichhorniae root, leaf, chalina, tealeaves.
Plant template can be for subsequent use after convection drying, also can be the salt acid soak 2-24 hour of 1%-8% with massfraction, and be washed till neutrality with ultrapure water, put into baking oven 60 DEG C of dry for standby.
Calcium salt described in the present invention is a kind of in calcium chloride, nitrocalcite, calcium carbonate.
The rate of addition of calcium salt described in the present invention is 1-10ml/min.
Calcining described in the present invention refers at 500-1000 DEG C of pyroprocessing 4-10h.
