Description
Technical field
The invention belongs to changing waste into resources and technical field of waste water processing, and in particular to one kind is based on dilute sulfuric acid and DDBAC
The method that combined pretreatment wheat stalk prepares Cadmium In The Water Body ion adsorbent.
Background technology
Cadmium is that one kind common are harmful heavy metal.Certain density cadmium would generally be contained in the case of nature in water body, this master
To derive from the weathering of soil and the leaching of rock.And the activity that water Cd pollution is also due to mainly the mankind is caused, including relate to
Cadmium industry a large amount of cadmium wastewater that such as metal smelt, plating, battery, printing and dyeing industry produce；The chemical fertilizer and pesticide of numerous species
Use；Random stacking of some discarded objects produced in the burning and daily life of fossil fuel etc., these are likely to
Cadmium is introduced into water environment, is polluted.Water Cd pollution can produce humans and animals very big harm, and cadmium enters people and moves
There is biological magnification and biological accumulation to act on after in object, a series of infringement is produced to kidney, liver, bone etc..This
Outside, cadmium also has certain toxic action to plant and microorganism.Therefore, water Cd pollution has more and more been weighed in recent years
Depending on water Cd pollution restorative procedure has also been continuously available renewal and development.
Traditional water Cd pollution recovery technique is concentrated mainly on physics, chemistry, three aspects of biology.But in view of it is economical,
Many factors such as environmental protection, efficiency, people increasingly pay attention to using the restoring cadmium polluted water body of bioremediation technology.As agriculture
Crop principal by product, stalk are an important components in production estimation system.Agricultural crop straw rich in nitrogen, phosphorus,
The nutrients such as potassium, while also containing organic substances such as cellulose, hemicellulose and lignin, it is a kind of to serve many purposes
Renewable biological source.According to statistics, the whole world can produce 2,000,000,000 tons of agricultural crop straws every year.And China is big as an agricultural
State, the stalk amount produced every year there are about 700,000,000 tons.Since stalk derives from a wealth of sources, aboundresources, have become the important of recycling
Object.Cellulose contained by stalk, lignin and hemicellulose etc. contain exhibiting high surface active function groups, such as hydroxyl, carboxyl, carbonyl
Base etc. can be chelated with heavy metal ion such as cadmium ion, lead ions, the reaction such as ion exchange.In this way, can be with
Heavy metal toxin is extracted from contaminated water body.Therefore, stalk becomes a kind of common biological adsorption agent.But
Since original state stalk adsorption capacity is undesirable, how research become to improve its adsorption efficiency by different preprocess methods
Obtain hot spot.The invention discloses cadmium ion in a kind of diluted acid joint cationic surfactant pretreatment wheat stalk absorption water
Method, used adsorbent is cheap and easy to get, environmentally protective, and pretreatment mode is simple, and adsorption effect is good after processing, containing cadmium
There is preferable prospect in terms of ion waste water processing.
The content of the invention
A kind of method of diluted acid joint cationic surfactant pretreatment wheat stalk Adsorption of Cadmium, including following step
Suddenly:
(1) wheat stalk physical treatment：Wheat stalk is cut into segment first after collecting, and cleans, drying, powder
It is broken, sieving；
(2) wheat stalk Chemical Pretreatment：The stalk of first step processing is immersed into a period of time in dilution heat of sulfuric acid, then
A few hours are vibrated, are cleaned to neutrality, immerse a period of time in cationic surfactant solution after drying again；
(3) cleaning treatment：The pretreated wheat stalk of second step is washed away into remaining chemical reagent using deionized water,
Then it is dried for standby；
(4) adsorption experiment：Pretreated stalk is immersed in certain density cadmium-ion solution, when reaching adsorption equilibrium
Between after after sampling filtering with the concentration of atomic absorption spectrophotometer measure cadmium ion.
Preferably, the segment length that wheat stalk is cut into step 1) is 1~3cm, and drying temperature is 80 DEG C, and the time is
24h, sieve for 100 mesh sieves.
Preferably, dilution heat of sulfuric acid mass fraction used is 2% in step 2), and stalk is 1 with dilution heat of sulfuric acid solid-to-liquid ratio:
10, soaking time 24h, hunting speed 150r/min, duration of oscillation 2h.Double DDBAC concentration are 2.5mmol/L, processing
Time is 3h.
Preferably, cleaned to cleaning solution pH and be in neutrality using deionized water in step 3).
Preferably, cadmium-ion solution concentration handled in step 4) is 15mg/L.
It is further preferred that major pollutants are Cd (NO in stalk processing cadmium wastewater in step 4)3)2。
Compared with prior art, the invention has the advantages that：
(1) Adsorption for heavy metal in water is allowed to of low cost by the present invention, environmentally protective；
(2) present invention is with based on cadmium ion in diluted acid joint cationic surfactant pretreatment wheat stalk absorption water
Method absorption water in cadmium ion effect it is good, no coupling product, clean environment firendly is energy-efficient；
(3) the wheat stalk raw material in the present invention is simple and easy to get, and pretreatment operation is simple, of low cost, green non-pollution.
Brief description of the drawings
Fig. 1 is that a kind of diluted acid combines the method absorption water that cationic surfactant pre-processes wheat stalk Adsorption of Cadmium
