Abstract
The invention discloses a method for preparing an adsorbent by modifying a tea by-product with hansenula microbes. The method comprises the following steps: crushing the tea by-product, mixing with the hansenula microbes, cultivating and modifying, and thus obtaining the adsorbent. The adsorbent is used for adsorbing formaldehyde, benzene and methylbenzene. In the cultivating process, the hansenula microbes grow to ferment cellulose, pectin and terpene in tea powder, oxidation, degradation, decomposition and cracking are generated, therefore the surface chemical property and the pore structure of the tea by-product are modified, and the synchronous improvement of the chemical adsorption performance and the physical adsorption performance of the adsorbent is facilitated. Through determination, in the space with the adsorbent, the decent degree of formaldehyde, benzene and methylbenzene is obvious. Thus, the modification of the hansenula microbes improves the adsorption performance of the tea by-product.
Description
Technical field
The present invention relates to the modified field of tea by-product, more particularly to a kind of modified Folium Camelliae sinensis by-product of Hansenula yeast microorganism belonging to genus
The method that thing prepares adsorbent.
Background technology
Folium Camelliae sinensis are the large agriculture and forestry by-products of China, and irreplaceable fundamental role is played in national economy.With
The development of Tea Industry, will bring the substantial amounts of just processing byproduct such as aged Folium Camelliae sinensis, stalky tea and tea dust.If these tea by-products
Cannot be comprehensively utilized, the great wasting of resources and economic loss will be caused.Recycling for tea by-product both contributed to
Adjustment tea industry structure, extends tea industry chain, can increase tea grower's income again, solve " rural economy, rural development and rural demography ", improve numerous tea growers and enterprise
The plantation of industry, processing, enthusiasm is managed, meet the policy for helping agriculture to increase income and develop agricultural industrialization, also complied with China for a long time
The developing goal of scientific and technological development planning outline.Therefore, the comprehensive utilization of tea by-product has important social meaning,
It is the work for having strategic importance.
At present, application of the tea by-product on environmental-protection adsorption field mainly has three kinds of modes：Directly utilize, carbonization is modified
It is modified with chemical drugss.It is directly poor using the removal effect to polluter, although carbonization is modified and the modified energy of chemical drugss
Absorption property is effectively improved, but destroys the fragrance of Folium Camelliae sinensis itself.
The comprehensive utilization of tea by-product is mainly able to extensive exploitation utilization in fields such as food, chemical industry, medicine and building materials,
And obtain remarkable effect.In view of Folium Camelliae sinensis are a kind of materials with network structure, porous, and it is living containing substantial amounts of polyhydric phenols etc.
Property hydroxyl, its application in environmental-protection adsorption field are more and more extensive.Amarasinghe etc. adopts tea by-product adsorption aqueous solution
In copper ion and lead ion.As a result show, in pH value 5-6 scopes, tea by-product has preferable absorption property, initial
15-20 minutes, clearance is up to 90%.Wang Jinquan etc. is modified to adhesive using Aqua Folium Camelliae sinensis, and is coated on plywood
On, measure burst size of methanal, bonding strength and decocting in water and come unglued the time.Result of study shows that Aqua Folium Camelliae sinensis are modified, plywood
Burst size of methanal is effectively reduced, and the time of coming unglued is improved, and intensity is barely affected.In order to further improve tea
The absorption property of leaf, Gokce etc. prepare activated carbon using Folium Camelliae sinensis, and are modified with nitric acid, and modified product is used to adsorb
Methylene blue and phenol.As a result show, be modified and increased the oxygen-containing functional group of activated carbon surface, basic functionality and carboxylic-acid functional
The absorption of group inhibitory activity charcoal Pyrogentisinic Acid.Auta etc. prepares Folium Camelliae sinensis residue activated carbon using potassium acetate activation, for adsorber acid
Property indigo plant 25.As a result show, activated carbon is up to 97.88% to the adsorption rate of acid blue 25.Nine red grade of official with Folium Camelliae sinensis powder as raw material,
Carbonization at 250-400 DEG C is obtained Folium Camelliae sinensis carbide.Result of study shows, as the adsorptive value of the rising of temperature, ammonia and formaldehyde is in
The trend now fallen after rising, reaches maximum, and benzene adsorptive value is presented the trend for constantly rising at 300 DEG C.Yang etc. adopts alkali
Modified Folium Camelliae sinensis residue, for the lead ion in adsorption aqueous solution.Result of study shows that modified Folium Camelliae sinensis have flourishing hole
Structure.Huang Yang etc. adopts hydrochloric Acid Modification Folium Camelliae sinensis powder, and adsorbs crystal violet solution to which and study.As a result show, modified tea
Leaf powder reaches 98% to the clearance of crystal violet.Zhao Xiuqin etc. is modified to tealeaf residue using formaldehyde and is used to adsorb in waste water
Heavy metal chromium.As a result show, modified formaldehyde tealeaf residue has good adsorption to chromium.As a result show, ferric chloride concn
For 0.3mol/L when treatment effect preferably, adsorption process meets Freundlich models.In sum, it is modified simultaneously using microorganism
Tea by-product, and the research of adsorbing domain is applied to, it is rarely reported both at home and abroad.Although carrying by carbonization and chemical agent are modified
The high absorption property of Folium Camelliae sinensis, but destroy the fragrance that Folium Camelliae sinensis have in itself.
The content of the invention
The goal of the invention of the present invention is to solve above-mentioned technical problem, there is provided one kind is entered to tea by-product using microorganism
Row is modified, can improve the sorbent preparation method that tea by-product absorption property can keep its fragrance again.
