Abstract
The invention relates to a preparation method of Eucommia ulmoides active carbon, and belongs to the preparation of inorganic material active carbon in the material field. The method comprises the following steps: juicing green Folium Eucommiae, carrying out alkali solution immersion and ultrasonic treatment on stems and branches to preliminarily destroy the cell wall structure, mixing with the obtained Folium Eucommiae juice, stacking the obtained mixture to reserve the medicinal and health effective components of Eucommia ulmoides as possible, and carbonizing to obtain an activate carbon product. The method makes full use of biomasses generated in the cultivation of the Eucommia ulmoides, and the active carbon produced in the invention still reserves a small amount of the medicinal and health components of the Eucommia ulmoides. Compared with present active carbon prepared by using wood materials, the active carbon prepared in the invention has higher porosity, and is more suitable for being applied in the field of foods.
Description
Technical field
The present invention relates to the preparation field of inorganic materials gac, specifically a kind of preparation method of bark of eucommia gac.
Background technology
The bark of eucommia is China's rare traditional Chinese medicine, has the cultivation history of more than 2,000 year in China, and its bark has very high pharmaceutical use, belongs to famous and precious tonic herb, and its taste is sweet, warm in nature.Have tonify the liver and kidney, strengthen muscles and bones, recuperating CHONG and REN meridians, solid through antiabortive effect.Can treat the pain in the waist and lower extremities or aching and limp unable that insufficiency of kidney-YANG causes, born of the same parents' tire that deficiency of liver-QI causes is solid, and scrotum is wet the disease such as to itch.Be listed in top grade in Shennong's Herbal.Folium Eucommiae is the raw material making Eucommia Tea, and Eucommia Tea has very high health value.The modern study bark of eucommia has rubbish in purged body, strengthens human body cell substance metabolism, prevents muscle skeleton aging, balanced human's blood pressure, decomposer inner cholesterol, reduces body fat, recovers blood vessel elasticity, diuresis heat-clearing, broad-spectrum antimicrobial, stimulating central nervous system, improves white cell pharmacological action.
Gac is a kind of solid carbonaceous of black porous, and main component is carbon, and containing elements such as a small amount of oxygen, hydrogen, sulphur, nitrogen, chlorine.The specific surface area of normal activated carbon is at 500 ~ 1700m
2between/g, having very strong absorption property, is a kind of industrial adsorbents that purposes is extremely wide, in addition, also has decolouring and filtration, absorbs the effects such as various gas and steam.
Summary of the invention
The object of this invention is to provide a kind of preparation method of bark of eucommia gac, not only open up the purposes of the bark of eucommia, make full use of the biomass (branches and leaves etc. as dry branches and fallen leaves, pruning) produced in cultivating eucommia, and the gac produced is compared with the gac that conventional wood material is produced, there is certain medicine and health care effect, the convenient absorption for pigment in food service industry.
For achieving the above object, technical scheme provided by the invention is: a kind of preparation method of bark of eucommia gac, comprises the following steps:
1) choose the green blade clean water of the fresh bark of eucommia clean, then adopt the mode of mechanical expression to process it, collect the squeezing material cake and juice that obtain, for subsequent use;
2) choose in the bark of eucommia limb after the branch of the bark of eucommia and peeling one or both, 20-30 order is crushed to after cleaning, and be dipped into that mass concentration is 25-35%, temperature is 3-5h in the sodium hydroxide solution of 40-50 degree Celsius, ultrasonic wave is applied to it after immersion, hyperacoustic applying mode is: first apply the ultrasonic wave 1min of frequency 350-370KHz to it and stop 0.5min, apply ultrasonic wave 1min that frequency is 100-120KHz again and stop 0.5min, the above-mentioned hyperacoustic applying process that circulates 2-3 time, filtration obtains pressed powder, for subsequent use;
3) by squeezing material cake, the step 2 in step 1)) in pressed powder and the bark of eucommia fallen leaves that clean up and the juice that obtains in step 1) be after the ratio mix of 8-10:1, be deposited in 48-60h in temperature is 40-50 degree Celsius, relative humidity is 90-95% greenhouse according to weight ratio, for subsequent use;
4) step 3) being joined mass concentration through the mixture stacking process according to the ratio that weight ratio is 1:1-1.5 is flood in the phosphoric acid solution of 40-50%, and dipping temperature is 60-70 degree Celsius, and dipping time is 1-2h, for subsequent use;
5) activate in mixture complete for dipping feeding activation furnace, during activation, first be warming up to 170-190 degree Celsius, and keep this temperature 2-3h, and then continue to be warming up to 480-500 degree Celsius, and keeping this temperature 1-2h, cooling after washing is to neutral, and crushed after being dried to 200 order i.e. obtained product.
The bark of the described bark of eucommia selects perennial bark or the above trunk bark of life in 6 years, and the branch chosen can be withered branch, also can be to prune the branch dropped.
In the present invention, in steeping process, applying frequency every 20min to it is the ultrasonic wave 30s of 510-530KHz, until flood complete, in steeping process, applies ultrasonication, can significantly improve void content and the adsorption effect of gac.
Beneficial effect: bark of eucommia greenery are first squeezed the juice by the present invention, and then by branch and limb dipping by lye and ultrasonication, its cell wall structure of preliminary destruction, then process stacking after itself and bark of eucommia juice mix again, retain the effective constituent of its medicine and health care as much as possible, finally carrying out carbonizing treatment again obtains activated carbon product, not only make use of the biomass produced in cultivating eucommia fully, and in final obtained gac, also remain with the small part medicine and health care composition of the bark of eucommia, be compared to the gac that existing wood materials is made, void content is higher, be more suitable for being applied to field of food.
