Abstract
The invention discloses a kind of preparation method of environment friendly biological adsorbent, it is using the fiber and pericarp of plant or fruits and vegetables as primary raw material, sequentially pass through get the raw materials ready, boiling, squeezing, rinsing, alkaline reaction, the step such as drying and crushing are prepared from, raw material sources of the invention are extensively, cheap and easy to get, the recycling of discarded object can be realized, preparation process is simple, and process is easily controllable, easy to operate, the adsorbent of preparation is loose porous, advantages of good adsorption effect.The present invention is suitable as adsorbent and is used for adsorbing gas with foreign flavor or formaldehyde.
Description
Technical field
The invention belongs to family expenses absorbent fields, it is related to a kind of preparation method of environment friendly biological adsorbent.
Background technology
Indoor air pollutants include some indoor toxic and harmful gas, such as formaldehyde, benzene, ammonia, oxycarbide.Formaldehyde is made
One of major pollutants for room air, are also the pollution pollutant that most universal, most serious, people most pay close attention to, and it originates wide
It is general.Domestic and international numerous studies show that a large amount of ornament materials, furniture and the coating used in fitment process is room air pollution
Main release source, such as building structural materials and ornament materials.Formaldehyde is primarily present in the deep of ornament materials, with release speed
Degree is slow, and the feature such as release time length, current adhesive is various in style, in decoration using it is most be arteries and veins urea formaldehyde, mainly
Urea and formaldehyde condensation reaction are formed, and it is the main reason for causing formaldehyde in indoor air exceeded.
With the improvement of people's life quality, the problem of indoor air purification turns into people's general concern.And formaldehyde is made
For the number one killer of room air, the huge concern of people is caused.It is able to can be sent out in furniture in room, such as cabinet, bookcase
Go out formaldehyde, and the volatilization of formaldehyde is a slow process.The formaldehyde of Long Term Contact low concentration, can be caused very to human health
Big threat.So solving the most important thing that Formaldehyde Pollution of Indoor Air is Indoor Environment Treatment.
At present, the domestic method except formaldehyde mainly uses the pure PARA FORMALDEHYDE PRILLS(91,95) of some activated carbons sold on the market, diatom to carry out
Absorption, but the cost of these materials is higher, and their absorption is limited, easily causes secondary pollution.Therefore I
Can be using this not only economical and practical but also healthy material of fragrant citrus pericarp come formaldehyde adsorption.In life we have seen that fragrant citrus pericarp lettuce
Bamboo shoot leaf, watermelon peel etc. are not used effectively, and it is both twice laid to be utilized to formaldehyde adsorption, is conducive to human health again.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of preparation method of environment friendly biological adsorbent, raw material sources are extensive,
It is cheap and easy to get, the recycling of discarded object can be realized, preparation process is simple, and process is easily controllable, easy to operate, preparation
Adsorbent is loose porous, advantages of good adsorption effect.
Technical problem solved by the invention is realized using following technical scheme：
A kind of preparation method of environment friendly biological adsorbent, it is carried out successively according to steps order：
（1）Get the raw materials ready
It is material to choose watermelon peel, fragrant citrus pericarp, sleeve skin, big wheat husk, straw, and segment or fritter are cut into after being cleaned, is obtained
A；
（2）Boiling
A is placed in boiling 50min in boiling water；Obtain B；
（3）Squeezing
B is placed in beater, material slag is squeezed into, obtains C;
（4）Rinsing
C is filtered, and is taken filter residue to be rinsed with circulating water to neutrality, is obtained D；
（5）Alkaline reaction
By the cornstarch of D weight 1/2 and the water of D weight 1/2 in pot, it is gelatinized at 30 DEG C；
Take D to be soaked in the alkali lye that PH is 12, add dextrin, in the lower reaction 6h of 60 DEG C of stirrings, obtain E；
In this step, graft reaction occurs for rich fibrous filter residue and the corn of gelatinization, generates the vapour with spatial networks
The spacial framework in oilhole road；
（6）Dry
It is placed in after E is taken out in drying box in drying 24h at 80 DEG C, obtains F；
（7）Crush
After F is crushed, produce.
It is used as the restriction of the present invention：
Step（5）In, described alkali lye is NaOH；
Step（5）In, described gelatinization time is 20min.
The present invention also has a kind of restriction, step（7）In, 100 mesh sieves are crossed after crushing.
Compared with prior art, the advantage of the invention is that：The preparation method for the environment friendly biological adsorbent that the present invention is provided,
Raw material sources are extensively, cheap and easy to get, can realize the recycling of discarded object, and preparation process is simple, and process is easily controllable, behaviour
Make easy, the adsorbent of preparation is loose porous, advantages of good adsorption effect.
The present invention is applied to gas with foreign flavor and formaldehyde in adsorption chamber.
