Description
Technical field
The invention belongs to sorbing material technical field, and in particular to a kind of Fe-Mg-La tri compounds fluorine ion absorber and
Its preparation method.
Technical background
[become more meticulous with the rapid development of economy, fluoride pollution has become one of primary pollution source of China's environmental pollution
Work, 2013.30 (1) 82-83].Multiple industries such as glass, electronics, chemical fertilizer, smelting, agricultural chemicals, garbage disposal and thermal power generation
Substantial amounts of fluoride waste can be all discharged in production process, if dealing with improperly, serious pollution and harm [industry can be caused to environment
With water and waste water, 2013.44 (4):18-20].In recent years, some serious diseases triggered by fluoride pollution are so that people are dirty to fluorine
The problem of dye, increasingly payes attention to [environmental project journal, 2016.10 (5):2262-2264], because fluorine ion is easily soluble in water, pole
Easily underground water is polluted, Oil repellent has become an important indicator [Applied Surface of measurement water quality
Science ,357(2015):91-100].The world, which defends tissue and Environmental Protection Administration, strict restriction to the fluorinated volume of drinking water, according to
It provides that fluoride ion in drinking water appropriate concentration range is 0.5-1.5mg/L, and Chinese safe drinking water standard fluorinion concentration
No more than 1.0mg/L [Journal of Chemical Industry and Engineering, 2016.67 (4) 1372-1376].Therefore, the technology of Fluoride Removal meaning for developing the economy economical
Justice is great.
In numerous drinking water defluorination methods, absorption method is before its is simple, easy to operate, cost is low be considered as most to have
The method on way.For example, patent [a kind of preparation method of de-fluoridation adsorbent, 201310183225.0] proposes a kind of Ni-Mg-Al
Houghite de-fluoridation adsorbent, with preferable adsorption-defluorination effect, but the preparation process of material needs high-temperature calcination, is prepared into
This is higher；Patent [methods for making and using same of high-efficiency defluorinating adsorbent, 200710176919.6] proposes a kind of iron-manganese concretion
Class de-fluoridation adsorbent, fluorine removal is more than 90% under the conditions of pH=5-7, but the material belongs to support type granule adsorbent, and material exists
Active component during use easily comes off, and stability of material is poor；A kind of patent [composite metal oxide de-fluoridation absorption
Agent, application number 200510116751.0] propose a kind of composite metal oxide de-fluoridation adsorbent there is preferable defluorination effect,
But aluminium is as one of maximally efficient composition of the adsorbent, applicable pH range may be caused narrower and the easy dissolution intoxicating of aluminium.
Under this technical background, we have developed, and a kind of cost is low, efficiency high fluorine ion absorber, and the adsorbent is adapted to
Scope is wide, can be maintained at more than 90% to the clearance of fluorine, highest clearance reaches 98.5% in pH=2-7 wide scope.This
Described a kind of Fe-Mg-La tri compounds fluorine ion absorber of invention and preparation method thereof, has no relevant report.
The content of the invention
It is an object of the invention to provide a kind of Fe-Mg-La tri compounds fluorine ion absorber and preparation method thereof, this hair
Bright realized using following means：
（1）By Fe3+, Mg2+, La3+Salt be dissolved in deionized water, Fe, Ma, La mol ratio are 8:4:2；1:4:2；1:4:
0.5；4:4:2；1:4:1；1:25:4, the salt is sulfate or nitrate；
（2）Add NaOH regulation pH value so that produce precipitation, the scope of pH value is 2-7；
（3）Gained is precipitated, is aged at room temperature 24 hours, then filter and alternately washed with deionized water and ethanol 3 times with
On；
（4）Gained solid particle is dried 24 hours at 65 DEG C, fine-powdered is ground to form with agate mortar, that is, obtains product.
The advantage of the invention is that：Prepared fluorine ion absorber wide adaptation range, is adaptable to pH 2-7 scope,
High to the clearance of fluorine ion, highest clearance reaches 98.5%.And preparation condition is gentle, method is simple, and cost is low so that
Material is suitable for a wide range of popularization and application.
