Description
Technical field
It is more particularly to a kind of to be situated between in order for adsorbing the modified SBA-15 of lithium the present invention relates to ion adsorbing material field
Porous materials and preparation method thereof.
Background technology
Porous material has specific surface area higher, and the fields, root such as absorption, catalysis and separation are widely used in for a long time
Porous material can be divided into according to pore size：Poromerics, mesoporous material and large pore material.Ordered mesoporous material is in recent years
The new material of synthesis, with homogeneous adjustable mesoporous pore size, specific surface area higher, the skeleton structure of stabilization, it is easy to mix
Miscellaneous unformed skeleton, it is easy to the inner surface of modification, therefore can serve as functional material, adsorbent or catalyst and its load
Body.Ordered mesoporous material not only compensate for the deficiency of micro-pore zeolite molecular sieve, can also by the use of in material it is order mesoporous as
" microreactor ", prepares the nano material with property.
SBA-15 type ordered mesoporous materials, are the ordered mesoporous materials of a class excellent performance, are two-dimentional hexagonal structures, are had
Expansible large aperture and thicker hole wall, are that catalytic reaction and adsorbing separation reaction provide good carrier.SBA-15
Ordered mesoporous material be in acid condition, by the use of triblock copolymer oxide-polypropylene oxide-PEO as
Template, synthesizes with tetraethyl orthosilicate as silicon source.And in building-up process, can by change synthesis temperature, when
Between, the acidity of solution obtains the SBA-15 type ordered mesoporous materials of different pore size size.SBA-15 type ordered mesoporous materials
Aperture can be adjusted in the range of 2-30nm, therefore it receives much concern in the application of absorption and separation field.Can also be by right
SBA-15 type ordered mesoporous materials are modified, and make its functionalization, to adapt to different adsorption entails.
The method of modifying of SBA-15 type ordered mesoporous materials mainly has two kinds：One kind be hydro-thermal direct synthesis technique, be
Modifying agent is directly added into building-up process, modifying agent is combined after being hydrolyzed in synthetic system with the silicon skeleton of mesoporous material, then
Certain specific group is embedded on the skeleton of SBA-15；Another method is rear grafting, that is, refer in synthesis SBA-15
Afterwards, reacted with grafting by the active silicone hydroxyl on SBA-15 surfaces, most at last its grafting on SBA-15 skeletons.Latter
Method is big due to flexibility, and usable scope is wide, is presently the most conventional method of modifying.
Lithium is a kind of important rare metal, is widely used in the fields such as new energy, atomic energy industry, chemical industry space flight.With
The demand that people to lithium is increasing, only can not meet demand by extracting the lithium in solid-state lithium ore, therefore, to liquid
The extraction of lithium has very important significance.Treatment is modified by SBA-15 ordered mesoporous materials, makes its functionalization, from
And lithium that can efficiently in adsorptive liquid has Research Significance and practical value higher.
The content of the invention
It is an object of the invention to provide a kind of modified SBA-15 ordered mesoporous material for adsorbing lithium and preparation method thereof,
The modified SBA-15 ordered mesoporous material has stronger lithium adsorption function, in a liquid can isolate lithium, and the material
