Abstract
The present invention relates to a kind of complete preparation process of desulfurization iron-based material, are directed to the preparation for including tealeaf residue load iron-based material.Preparation method in the present invention is simple, and product price is cheap, has higher S2‑Adsorption capacity.
Description
Technical field
The present invention relates to a kind of complete preparation process of desulfurization iron-based material, are directed to include tealeaf residue load iron base material
The preparation of material.
Background technology
The fast development of chemical industry is made that indelible contribution, but also environment is made simultaneously for national economic development
Into huge pollution.Sulfur-containing waste water has a large amount of discharge, the poison of this kind of waste water in enterprises such as petrochemical industry, pharmacy and process hides
Property is big, and corrosivity is strong, irremediable loss can be caused to environment or even jeopardize the life of people, therefore no matter from safety, ring
Border or economic angle consider it is instantly urgently to be resolved hurrily for how preferably handling the sulfur-containing waste water that industrial enterprise gives off and becoming
The problem of.
It is more to the processing method of sulfur-containing waste water at present but high in the prevalence of operating cost or technology is jejune asks
Topic, and also there is a certain distance compared with foreign technology for domestic technique.For sulfur-containing waste water processing both at home and abroad all
There is more mature processing method, it is common to have oxidizing process, catalytic oxidation, precipitation method etc..
Sulphur-containing substance is widely present in the environmental protection facilities such as industrial processes, sewage treatment plant and refuse landfill and ran
Cheng Zhong, it is more to sulfur-containing waste water sulfur method at present, but due to the use of of high cost, limit its scope of application.
In view of the foregoing, a kind of desulfurization iron-based material is prepared, raw material environmental protection is easy to get, preparation process advantages of simple,
And function admirable.
Invention content
The present invention provides entire preparation process flow of iron-based composite adsorbing material and preparation method thereof, and method mainly has
One, the i.e. preparation of tealeaf residue load iron-based sulfur removal material.
It is an object of the invention to prepare iron base composite material, to solve the pollution problem of the sulfur-containing waste waters such as petrochemical industry, and drop
The use cost of low sulfur removal material.The present invention provides the preparation process for including preparing tealeaf residue load iron-based material.Present invention side
Method prepares the process problem that iron-based sorbing material effectively solves industrial sulfur-containing waste water, material excellent combination property, preparation method letter
It is single.
The present invention relates to a kind of preparation methods of tealeaf residue load iron-based material, and each component material is produced by different loads ratio
Material, the preparation method are made of following steps：Fresh tealeaves is boiled to clarification, drying, crushed, sieving by A；B is prepared
Certain density ferric chloride solution is reacted tealeaf residue powder with ferric chloride solution by different proportion mixed hydrogenation sodium hydroxide solution
And PH to 12 is adjusted, it is placed on magnetic stirring apparatus and is stirred；C, suction filtration washing is put after load is dried in vacuo in an oven；
D is put into after drying in mortar, is ground sieving pack.
The present invention has following significant advantage：First, product of the present invention has sulphion in absorption waste water well
Effect.It is simple for the tealeaf residue raw material of load in the present invention, of low cost, environmental protection.
Specific embodiment
With regard to specific embodiment, the present invention is described in further detail below
Embodiment 1
1. a kind of preparation method of tealeaf residue load iron-based material, step are as follows：
Fresh tealeaves is boiled to clarification, drying, crushed, sieving by A, and drying temperature is 120 DEG C, smashes it through 60 mesh sieve.
B, at room temperature, at a normal, by tealeaf residue powder and iron chloride in proportion 1:4 mixing are made into 40ml solution and add 2mol/L
Sodium hydroxide solution is impregnated and is stirred, and the time is 10 minutes, adjusts PH to 12, and suction filtration is washed to neutrality and is put into drying box.
C, vacuum drying, temperature are 60 DEG C.
D, ground 60 mesh sieve pack preservation after dry.
Claims (4)
1. a kind of preparation method of desulfurization iron-based material, it is characterized in that：Using tealeaf residue as raw material, loading type iron sill is prepared,
Include the following steps：
A. tealeaf residue is boiled, dried, crushed, be sieved；
B. ferric chloride solution is prepared, tealeaf residue powder is mixed with dipping in proportion with ferric chloride solution, adds in sodium hydroxide solution
