Description

The double-deck amino modified SiO inside and outside one kind2The synthetic method and its application of aeroge
Technical field
The present invention relates to adsorbent preparation technical field, specifically a kind of inside and outside double-deck amino modified SiO2The conjunction of aeroge At method and its application.
Background technique
The fast development of global economy has derived serious problem of environmental pollution, and it is sustainable that environmental pollution also becomes society A severe challenge in development process.In recent years, the water pollution based on hardly degraded organic substance is increasingly sharpened, developing low-cost, The processing method of green will be very crucial.In persistent organic pollutants, the high-enriched organics of humic acids are as rubbish The secondary pollution that rubbish treatment process generates, is always the difficult point of water treatment field.When the high concentration organic contamination of humic acids After object polluted water body, it will lead to water body chroma and the phenomenon that turbidity is got higher, body be complexed in humic acid, can increase its biology poison Property[1], meanwhile, humic acid can also be generated with chlorine-containing disinfectant reaction with " three cause effect " (mutagenesis, cause in disinfecting process Cancer and teratogenic effect) disinfection by-products[2]。
Currently, the method for processing humic acids high concentration organic contaminant has biochemical treatment process, advanced oxidation processes, for example, Photocatalysis, ozone oxidation, ozone+photochemical catalytic oxidation, catalytic ozonation and new material absorption method and membrane technology Deng[3-7].For humic acid pollutant in the percolate of " aging ", since the biodegradability of these pollutants is poor, so at biology It is substantially invalid to manage.Wu Wei et al. has studied TiO2Photocatalytic degradation humic acid, result of study show the degradation of humic acid be by For macromolecular acid to the process of small molecule acid, photocatalysis can not only make humic acid fade, and be also greatly reduced disinfection by-products Generation[8].But as the catalysis material of this quasi-tradition usually has two aspects: 1, most of photochemical catalysts It can be reacted using ultraviolet light, the visible light part of sunlight can not be utilized；2, catalyst is due to its tiny particle size It is easy to happen reunion, the reactivity number of sites of catalyst and pollutant is caused to reduce.The advantage of absorption method is its removal It is high-efficient, it is easy to operate, and will not usually generate side reaction and secondary pollution is generated to water body.Therefore, developing can have The photochemical catalyst adsorbent of excellent dispersibility and high-specific surface area is ten for processing humic acids high concentration organic contaminant Divide urgent and important.
The properties such as adsorption process and the surface nature of adsorbent material itself and material structure are closely bound up, and usually absorption divides again For physical absorption, chemisorption and ion exchange adsorption, often these three adsorption processes or two of them may all exist.Mesh Before, active carbon, zeolite molecular sieve and resinae adsorbent are using more extensive adsorbent.However, active carbon is primarily present Difficult life and being difficult to removes the problem of two aspects of hydrophilic small molecules substance, this causes it to be difficult to realize large-scale industrialization Using.Currently, high specific surface area silica aeroge becomes the hot spot studied at present.Aerosil is one kind by receiving Rice sized particles mutually polymerize the continuous three-dimensional net structure of formation, and the high dispersive full of air dielectric is light porous non-in hole Crystalline material.1931, Kistler professor's first passage sol-gel method of Stanford University prepared silica airsetting Glue [1].Aeroge is a kind of solid matter with micro-nano network structure, distinctive bigger serface, low-density, low-heat The characteristics such as conductance make it have huge application value in various fields.As researcher is to preparing silica airsetting Several aspects such as silicon source, modification, the characterization of glue are furtherd investigate, and aerosil is gradually in environmental improvement, catalysis, section Energy, drug loading, space industry etc. have broad application prospects.But how according to humic acids organic contamination pollutant It is key scientific problems of the invention that feature, which carries out efficient amino modified to aerosil,.
