Description
Technical field
The present invention relates to technical field of resource environments, it is more particularly to a kind of for remove Heavy Metals in Waters from
The preparation method of the biological adsorption agent of son.
Background technique
With the rapid development of economy, the living standard of the people increasingly improves, but it is dirty consequently also to produce a series of environment
Dye and water pollution.Unprocessed be stolen of a large amount of industrial wastewater is discharged into rivers,lakes and seas, to cause a large amount of water bodys contaminated, loses
Go the original value and effect of water body, water shortage situation is increasingly serious, per capita freshwater resources less than the world per capita 1/4.It is dirty at present
The heavy metal of dye water body mainly has mercury, lead and cadmium etc., these substances cannot be degraded by microorganisms after entering water body, through food chain
Enrichment 1,100 times can increase content in higher organism step by step, eventually enter into human body, cause no small wound to human body
Evil.Water pollution has become one of environmental issue instantly urgently to be resolved.
In the prior art, heavy metal ion mainly is adsorbed using substances such as Carbon fibe, carbon nanotube, graphenes, from
And achieve the purpose that water purification；Although effect is preferable, the preparation cost of these materials is high, and economic value is low, can not really promote
With it is universal, and be easy to cause secondary pollution.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide it is a kind of for remove Heavy Metals in Waters from
The preparation method of the biological adsorption agent of son, for the biological adsorption agent using bowl mandarin orange as raw material, bowl mandarin orange is at low cost, is easy to get；And it is right
Heavy metal ion has stronger suction-operated, and economic value is high.
To achieve the above object, the present invention provides following technical solutions：One kind is for removing Heavy Metals in Waters ion
Biological adsorption agent preparation method, include the following steps：

Bowl mandarin orange powder is made in middle grinding；
Step 2：Activating solution is configured, the activating solution is the KOH aqueous solution of 0.5mol/L；Bowl mandarin orange powder is immersed in work
Change in liquid and be uniformly mixed, obtains suspension；Then suspension is put into reaction vessel, then by reaction vessel be put into baking oven into
Row heat treatment；
Step 3：By the suspension elder generation acid-base neutralization after heat treatment, is then filtered, washed and dried, activated
Bowl mandarin orange powder afterwards；
Step 4：The bowl mandarin orange powder after activation is put into progress high temperature cabonization processing in atmosphere furnace again, after carbonization treatment
To biological adsorption agent.
The bowl orange peel will carry out mouldy processing, and concrete mode is that bowl orange peel is placed on 26-30 DEG C, and air humidity is
In the environment of 75-80%, place 20-30 days.
Every 10ml activating solution impregnates 0.1-0.2g bowl mandarin orange powder in step 2.
The concrete mode being uniformly mixed in step 2, which refers to, is mixed 10-20min in the case where revolving speed is 100rad/min.
The concrete mode being heat-treated in step 2 is to set oven temperature to 170-190 DEG C, and the processing time is 4-6h.
The concrete mode of acid-base neutralization is the aqueous hydrochloric acid solution that 0.1mol/L is added dropwise in step 3, until suspension
PH is 7.
The specific method of the high temperature cabonization processing is by 900-1100 DEG C of atmosphere furnace temperature setting, and the processing time is 3-
5h。
The preceding 10min of high temperature cabonization processing is being carried out in step 4, protective gas is constantly passed through into atmosphere furnace until carbon
Processing terminate for change, and the flow for being passed through protective gas is 0.3L/min.
The protective gas is any one in nitrogen, argon gas and helium.
The biological adsorption agent can be used for sewage treatment.
Beneficial effects of the present invention：It is at low cost by using bowl mandarin orange as raw material, and be easy to get, while bowl mandarin orange is a kind of life
Material, it is very friendly to environment, it is degradable, it not will cause secondary pollution, very economic, environmental protection.
In the present invention, mouldy processing first carried out to bowl orange peel, it is mouldy after bowl mandarin orange compared to usual bowl mandarin orange, its own
It will appear some holes, this is conducive to the heavy metal ion in adsorbed water body, is also ready for subsequent activation processing.It will hair
Bowl mandarin orange after mould cleans drying, is then ground to bowl mandarin orange powder, and the purpose of grinding is to increase the specific surface area of bowl mandarin orange, improves activation
Effect；Then bowl mandarin orange powder is activated, as one of innovation of the invention, activating solution selects potassium hydroxide water-soluble
Liquid can be obviously increased by the pore quantity on the activating solution treated its surface of bowl mandarin orange powder, and specific surface area significantly increases, greatly
Its adsorption capacity is improved greatly；Acid-base neutralization is first carried out after activation, is then filtered, is washed, is dry, carrying out the mesh of acid-base neutralization
Be to prevent KOH from can impact to subsequent carbonization treatment.
Bowl mandarin orange powder after drying carries out high temperature cabonization processing, concrete mode be bowl mandarin orange powder is put into porcelain boat, then
Porcelain boat is put into atmosphere furnace, high temperature cabonization processing is carried out to bowl mandarin orange powder；Before carbonization treatment, it is necessary to be held into atmosphere furnace
Continuous to be constantly passed through argon gas, argon gas plays the role of protection to bowl mandarin orange powder, prevents oxygen or carbon dioxide pair in air
Carbonization treatment interferes；It is 1000 DEG C by the temperature setting of atmosphere furnace as another new wound point of the invention, the processing time is
4h；Absorption property by the condition treated bowl mandarin orange powder is preferable；Bowl mandarin orange powder after carbonization treatment will become change
At biomass carbon, it will appear more hole and biggish specific surface area on biomass carbon, to the heavy metal ion in water body
With very strong suction-operated, while also extending the holding time.Final obtained biological adsorption agent to the heavy metal in water from
The removal rate of son reaches 80% or more, and purifying water effect is very good, can use as a kind of water-purifying material, while the biology material
Material is easy degradation, environmentally friendly, has good market prospects, easy to spread.
