Description
Technical field
The present invention relates to a kind of sodium alginate-MOFs complex microsphere preparation methods of absorption heavy metal arsenic, belong to water
Handle adsorbent preparing technical field.
Background technology
Arsenic is a kind of highly stable, nondegradable pollutant, be it is a kind of can long-term accumulated environmental contaminants.People
If be chronically in the environment containing arsenic, the decline of intelligence can be caused；For arsenic ion when body runs up to a certain amount of, people will
There are the slow poisonings such as phrenoblabia, headache.
MIL-101 has huge pore volume and specific surface area, and existing meso-hole structure also has micropore canals, can stablize and deposit
It is in air and water.And there is abundant functional group, be Pb in adsorbed water body2+Ideal material.But if directly will
MIL-101 is used for the arsenic ion in adsorbed water body, and adsorption effect is undesirable, only close with the adsorption effect of other sorbing materials
Seemingly, and do not have significant suction-operated.
Invention content
It is an object of the invention to overcome the shortcomings of the prior art, and it is simple to provide a kind of preparation process, user
Just, it can improve for Pb in water body2+Sodium alginate-MOFs complex microsphere the preparation methods of absorption property.
The purpose of the present invention is by following technical solution to complete, a kind of sodium alginate-of absorption heavy metal arsenic
MOFs complex microsphere preparation methods, the preparation method are：It is agitated in sodium alginate soln by the way that MIL-101 to be added
Afterwards, it adds CaCl2 aqueous solutions progress cross-linking reaction and obtains complex microsphere, be finally placed in microwaved in microwave reaction chamber obtain
To sodium alginate-MOFs complex microsphere water body purifying materials.
As preferred：The sodium alginate soln refers to：The sea that mass percent concentration is 0.5 ~ 3.0%, solvent is water
Solution of sodium alginate；The stirring refers to：It is stirred evenly at ambient temperature using magnetic stirrer, then air is removed through ultrasound
Bubble；The CaCl2 solution refers to：A concentration of 0.05 ~ 1.50mol/L, the CaCl2 solution that solvent is water；The microwave
Processing refers to：With 300W-1200W Power Processings 3-45 minutes.
The present invention is can form microballoon this property in calcium chloride solution based on sodium alginate, by sodium alginate with
MIL-101 is prepared into complex microsphere, can reach segregative purpose；
The sodium alginate has good balling-up, and MIL-101 is Pb in adsorbed water body2+Ideal material；It therefore will be extra large
Mosanom prepares complex microsphere after being mixed with MIL-101, and is applied in the absorption of arsenic in water body ion, prepares and easily divides
From and the good sorbing material of absorption property.
The present invention has preparation process simple, easy to use, can improve for Pb in water body2+The features such as absorption property.
Specific implementation mode
Below in conjunction with specific embodiment, the present invention will be described in detail：A kind of absorption heavy metal arsenic of the present invention
Sodium alginate-MOFs complex microsphere preparation methods, the preparation method is：It is molten by the way that sodium alginate is added in MIL-101
In liquid it is agitated after, add CaCl2 aqueous solutions carry out cross-linking reaction obtain complex microsphere, be finally placed in microwave reaction chamber and pass through
Microwave treatment obtains sodium alginate-MOFs complex microsphere water body purifying materials.
Embodiment as one preferred is：The sodium alginate soln refers to：Mass percent concentration be 0.5 ~
3.0%, solvent is the sodium alginate soln of water；The stirring refers to：It is stirred at ambient temperature using magnetic stirrer
It is even, then remove air bubble through ultrasound；The CaCl2 solution refers to：A concentration of 0.05 ~ 1.50mol/L, solvent are water
CaCl2 solution；The microwave treatment refers to：With 300W-1200W Power Processings 3-45 minutes.
The present invention is to be cross-linked to form complex microsphere by calcium chloride water after mixing sodium alginate with MIL-101；It should
Material combines sodium alginate and the common feature of MIL-101, achieves that separation by simple filtration, and MIL-101 has
There are the specific surface area of higher porosity and superelevation, surface to contain a large amount of carboxyl as functional group, these features are all advantageous
In the absorption to arsenic ion.
Other embodiments of the invention can be on the basis of disclosed above, can by the simple replacement of numerical value and feature
To obtain numerous embodiment, and those skilled in the art can simply implement this hair on the basis of understanding present disclosure
It is bright.
