Abstract
The present invention provides a kind of activated carbon supported titanium pillared montmorillonite composite material, and 1 is pressed by activated carbon and montmorillonite:3~3:1 weight ratio is combined.It is poor to solve existing heavy metal collection method treatment effect, easy to produce secondary pollution problems.The invention belongs to heavy metal recovery and field of composite material preparation.
Description
Technical field
The present invention relates to a kind of composite materials, belong to heavy metal recovery and field of composite material preparation.
Background technology
Heavy metal pollution threatens the health of the mankind.Often contain in the sewage that the industries such as mining, coloured, metallurgical and chemical industry are discharged
There are the heavy metal ion such as Pb2+, Cd2+, Cu2+.The heavy metal ion of human body excess intake can be poisoned, and cause anaemia, osteoporosis
And the diseases such as coronary heart disease.Therefore, reinforce very urgent to the processing of heavy metal ions in sewage.According to the removal of heavy metal ion
Mode is different, can the processing method of heavy metal wastewater thereby be divided into 2 major class：First, the heavy metal ion of solubilised state is transformed into not
Molten heavy metal compound, this method application is wider, but heavy metal recovery is more complex, and operating cost is higher；Second, not changing
It is concentrated and is detached in the case of heavy metal in waste water chemical form, this method is easily recycled heavy metal, but is wanted to technology
Ask higher.In general, all there is treatment effect in this 2 class method, secondary pollution etc. be easy tod produce, especially in heavy metal
When ion concentration is relatively low, often due to operating cost and the cost of raw material are excessively high and be difficult to carry out.
Absorption method is a kind of simple and practicable wastewater treatment method at present, using adsorbent surface-active by heavy metal from
Son removal, absorbing process is simply easily operated, has practicability, therefore be widely used in terms of wastewater treatment.
Invention content
It is an object of the invention to：A kind of activated carbon supported titanium pillared montmorillonite composite material is provided, it is existing heavy to solve
Metal recovery processes treatment effect is poor, easy tos produce secondary pollution problems.
To solve the above problems, quasi- use such a activated carbon supported titanium pillared montmorillonite composite material, by activity
Charcoal presses 1 with montmorillonite:3~3:1 weight ratio is combined.
Above-mentioned composite material presses 1 by activated carbon and montmorillonite:2 weight ratio composition.
Compared with prior art, activated carbon supported titanium pillared montmorillonite composite material of the invention not only has very organic matter
Good adsorption effect, and also have fine removal effect to heavy metals in industrial wastewater ion.
Description of the drawings
Fig. 1 is process flow chart prepared by composite material of the present invention.
Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
The detailed description of step, it should be understood that described herein specific examples are only used to explain the present invention, is not used to limit this hair
It is bright.
Embodiment：
With reference to attached drawing 1, the present embodiment provides a kind of activated carbon supported titanium pillared montmorillonite composite material, by activated carbon with
Montmorillonite presses 1:2 weight ratio composition, specific preparation method are as follows：
20g ca-montmorillonites are weighed, are dipped in 500ml distilled water, dispersion is stirred using magnetic stirring apparatus, are added
2.5g calgons stir 3h, stand 30 minutes, and with centrifuge (3600r/min) centrifuging and taking supernatant, constant temperature dries at 80 DEG C
Dry, ground 200 mesh sieve is to get to na-montmorillonite product.
4g na-montmorillonites are weighed, is added in 400ml distilled water and is dispersed with stirring into a concentration of 1% suspension, by 10ml
Absolute ethyl alcohol, 10ml butyl titanates and 2ml glacial acetic acids are uniformly mixed and are made into A liquid, and the HCl and 5ml of 24ml0.1mol/L is anhydrous
Ethyl alcohol is mixed into B liquid, under magnetic stirring, is slowly dropped into A liquid B liquid with the speed of a drop per second using rubber head dropper, obtains
8ml 1mol/LNaOH are added into colloidal sol immediately to yellow transparent colloidal sol and change soda acid ratio, then strong stirring at room temperature
30min stands 6h, obtains required pillaring agent.
Pillaring agent is transferred in na-montmorillonite suspension, is vigorously stirred, and the 2mol/L NaOH of 8ml are added toward it
PH of mixed is adjusted, 6h is stirred at room temperature, obtains C liquid.Mechanical lapping, sieving are carried out to activated carbon, extracting screen underflow is put into burning
In cup, 30ml concentrated nitric acids are added and impregnate for 24 hours, then are washed with distilled water to neutrality, dries, obtains the active powdered carbon of not grey matter
End.It weighs active carbon powder to be slowly added in C liquid, 3h is vigorously stirred on magnetic stirring apparatus, stand 12h, filtering is roasted
It burns, obtains activated carbon supported titanium pillared montmorillonite.
When prepared by suspension, the calgon of addition not only acts as peptizaiton, and providing sodium source makes calcium base cover
The interlayer calcium ion of de- stone is replaced by sodium ion, to generate na-montmorillonite by sodium.The crystal structure of montmorillonite is by two
Layer silica (Si-O) tetrahedral sheet presss from both sides one layer of alumina (Al-O) octahedral sheet is constituted 2:1 type layer silicate mineral, it is de- when covering
When stone is by mechanical force, hydroxyl bond meeting portion fractures in lattice end face keep lattice negatively charged, this negative electrical charge is usually by layer
Between in domain hydrated cation balance, i.e., be often full of nH2O+Mm+ (M is exchangeable ion) in TOT and TOT interlayers, so they
Interlamination region have good ion-exchange performance and Molecular Adsorption feature；Roasting is that activated carbon supported titanium pillared montmorillonite is compound
The critically important part of material preparation, under the high temperature conditions, the Ti ionic oxide formations reaction between montmorillonite layer generate TiO2 cylinders, increase
Big interplanar distance, activated carbon surface ion forms stable compound with montmorillonite surface, by montmorillonite-loaded in activated carbon table
Face will not change the physics and chemical characteristic of two kinds of materials, both active carbon surface absorption, while have titanium pillared montmorillonite
The characteristics of Inter layer adsorption.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
