Description
Technical field
It is more particularly to a kind of for removing the life of Heavy Metals in Waters ion the present invention relates to water treatment field
The preparation method of material.
Background technique
Since the mankind are increasingly frequent to industrial activities such as exploitation, the smeltings of heavy metal, the various human survivals that endanger is caused to be good for
Problem of environmental pollution of health, including heavy metal atmosphere pollution, heavy metal water body pollution, soil pollution by heavy metal etc., wherein water body
Pollution has the characteristics that big, difficult to control, the easy diffusion in region, and makes serious danger to human body by approach such as food chain concentration or drinking-water
Evil.The heavy metal ion such as Pb, Cd, Cu, Ni, which enter human body, to be combined with biological enzyme, and then inhibit protein synthesis, induce egg
White matter denaturation, and interfere nervous system.The situation is tense for heavy metal water body pollution, become environmental issue instantly urgently to be resolved it
One.
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 material of son, this method are at low cost and right by the way that using red bayberry as raw material, red bayberry is easy to get
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 material preparation method, include the following steps:
Step 1：Red bayberry is cleaned, drying in oven is then placed in, stoning milling obtains red bayberry powder；
Step 2：Red bayberry powder is put into progress high temperature cabonization processing in atmosphere furnace；
Step 3：Activating solution is configured, activating solution is the phosphate aqueous solution of 1mol/L, and red bayberry powder is taken to be immersed in activating solution
It is uniformly mixed, obtains suspension；Suspension is put into reaction vessel, then reaction vessel is put into baking oven and is heat-treated；
Step 4：Suspension after heat treatment is first neutralized with alkali, filtering and washing, washing then are carried out to suspension
After dry, obtain biological material.
The specific method of the high temperature cabonization processing is by 800 DEG C of atmosphere furnace temperature setting, and the processing time is 2h.
The preceding 10min of high temperature cabonization processing is being carried out in step 2, 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 0.4L/min.
The protective gas is any one in nitrogen, argon gas and helium.
The concrete mode being uniformly mixed in step 3 is that 5min is mixed in the case where revolving speed is 200rad/min.
The concrete mode being heat-treated in step 3 is to set oven temperature to 160-200 DEG C, and the processing time is 4-6h.
It with the concrete mode that alkali is neutralized is the KOH aqueous solution that 0.1mol/L is added dropwise in step 4, until suspended
The PH of liquid is 7.
The concrete mode washed in step 4 is first to be cleaned one time with deionized water, then with washes of absolute alcohol one time.
The biological material can be used for sewage treatment.
Beneficial effects of the present invention：By the way that using red bayberry as raw material, red bayberry is a kind of fruit that southern summer is common, because of its battalion
It supports and enriches, it is tasty, it is deep to be liked by southerner, while its production cost is low, is easy to get；Again because red bayberry belongs to berry
Class fruit, maturity period concentrate, and temperature is higher when mature, and storage life is short, and a large amount of red bayberry causes because sale is not fallen and rots
Greatly loss；By can be greatly improved the utilization rate of red bayberry as raw material using the red bayberry that do not sell, while red bayberry is
A kind of biological material, it is degradable, it not will cause secondary pollution, very economic, environmental protection.
In the preparation, first red bayberry is eluted with water, removes the sundries on red bayberry surface, is then placed in drying in oven, baking oven
Temperature is 60 DEG C, drying time 15min；Remove red bayberry core after drying, is put into grinding in mortar and obtains red bayberry powder；Grinding has
Conducive to the specific surface area for increasing red bayberry powder, prepare for subsequent carbonization treatment；Then red bayberry powder is put into porcelain boat, then
Porcelain boat is put into atmosphere furnace, high temperature cabonization processing is carried out to red bayberry 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, prevents oxygen or carbon dioxide in air from making to carbonization treatment
At interference；It is 800 DEG C by the temperature setting of atmosphere furnace when carbonization treatment, the processing time is 2h, passes through carbonization treatment, waxberry powder
End will become biomass carbon, and this biomass carbon has more hole and biggish specific surface area, can be good at absorption weight
Metal ion is also conducive to save；Temperature is excessively high or too low, can all influence pore quantity, to reduce adsorption capacity；Then right
Red bayberry powder is activated, and as key of the invention, selects phosphate aqueous solution as activating solution, concentration 1mol/L, to poplar
Plum powder is activated, and after being activated, the pore quantity of red bayberry powder can be obviously increased, and specific surface area obviously increases
Greatly, its adsorption capacity is greatly improved；By the way that embodiment 1 compares with comparative example 3-7 it is found that being activation with phosphate aqueous solution
When liquid, the adsorption capacity for the red bayberry powder that can just greatly improve, and when activating solution select calcium chloride water, hydrochloric acid, acetic acid or
When person's potassium hydroxide, the influence to red bayberry powder suction-operated is smaller；This is because on the one hand making into the phosphoric acid inside raw material
For catalyst the macromolecular key in red bayberry is broken, being crosslinked for key is on the other hand participated in by the polycondensation of itself and cyclisation,
Accelerate the generation for inhibiting tar while the fracture of carbon key, and produce the pore structure being dealt into, to improve the adsorption capacity of red bayberry；
Specific activation method is first to immerse red bayberry powder in activating solution to be uniformly mixed, and obtains suspension, suspension is put into reaction kettle
In, then reaction kettle is put into 180 DEG C of baking oven, place 5h.
Acid-base neutralization is first carried out after activation, then filtering and washing, be dried at room temperature for, obtain that there is water purification effect
Biological material finds that the biological material reaches 80% or more to the removal rate of heavy metal ion in water, water purification by examining
Effect is very good, can be used as a kind of water-purifying material, and the biological material can be made to be easy degradation, environmentally friendly, has fine
Market prospects, it is easy to spread.
