Description

A kind of lead ion seperation film and preparation method thereof
Technical field
It is specially a kind of by mesoporous SiO the present invention relates to a kind of lead ion seperation film and preparation method thereof2Microballoon and Kynoar (PVDF) PVDF/SiO obtained from blending film forming2Composite membrane and preparation method thereof, belongs to membrane material preparation science and is led with technology Domain.
Background technology
Lead is that distribution is wide, has accumulative heavy metal environmental contaminants.Lead be primarily present in metallurgy, printing, plating, machine-building, In the industrial production wastewaters such as chemical pharmacy, PETROLEUM PROCESSING, coating, weaving.Lead and soluble lead salt are poisonous, to human body and dynamic plant Thing can cause to seriously endanger：Lead can poison the nerve and hemopoietic system of people, cause spasm, neural blunt and anaemia etc., especially Influence the development of children；Harm of the lead to plant is mainly absorbed into plant by plant root, influences the growth of plant Development, causes the withered and dead of plant when serious.Lead contamination in waste water is increasingly serious with industrialization development, has caused The highest attention of people.In the industry productions such as plating, printing, lead-acid battery, mining, coating, lead wastewater treatment and synthesis The major issue for having become industry using reclaiming.
At present, the processing method of lead-containing industrial wastewater mainly has chemical precipitation method, ion-exchange, absorption method etc..These methods Although comparative maturity, cost is universal higher.Film absorption method is due to having the advantages that mode of operation is easy and secondary pollution is small in recent years It is significant for economically handling lead waste water more and more to be paid attention to.Adsorption function film can not only pass through Absorption heavy metal ion is quickly removed, and can repeatedly rapid regeneration and keep preferable adsorption capacity.However, research is found In polymer film most of chelation group can not Adsorption of Heavy Metals ion, film adsorption capacity is low, and effect is unsatisfactory.It is poly- Vinylidene (PVDF) is as a kind of combination property good microfiltration membranes or ultrafiltration membrane material, with high temperature resistant, and radiation hardness is wear-resisting, Characteristics such as (except highly basic) resistant to chemical etching, is widely used to chemical industry, and electronics is weaved, food, the field such as biochemistry.But PVDF Film cannot be directly used to heavy metal ion adsorbed, and Organic functional groups are modified obtained pvdf membrane also because modified group is in use Usually shielded and there is the small defect of the heavy metal ion adsorbed capacity of film.
Mesoporous silicon oxide (SiO2) there is good chemical stability and anti acid alkali performance energy and very big specific surface area, it is relative Big aperture and regular pore passage structure, while its aperture can be easy in continuously adjustabe, duct and surface in the range of 2 to 50nm It is modified, it is a kind of superpower adsorbent of adsorption capacity.But mesoporous silicon adsorbent is powder, is usually caused in use because of reunion Adsorption capacity declines；In addition, its particle diameter is smaller, operate with it is costly, it is extremely inconvenient.
Present invention incorporates mesoporous silicon oxide heavy metal ion adsorbed aspect characteristic and pvdf membrane it is porous, easy to use Etc. advantage, film forming is blended in inorganic nano-particle mesoporous silicon dioxide micro-sphere and PVDF, a kind of new PVDF/SiO is prepared for2 Composite membrane, for the separation of heavy metal lead ionic adsorption.
The content of the invention
Low the invention aims to solve adsorbed film adsorption capacity, mesoporous silicon oxide is easily reunited, in-convenience in use the problems such as, A kind of lead ion adsorbed film and preparation method thereof is provided, particular by preparing amino functional mesoporous silicon dioxide micro-sphere first, Then it is blended with PVDF, the PVDF/SiO of high adsorption capacity is made2Composite membrane.
The technical scheme that the present invention solves the product preparation method technical problem is：Design a kind of preparation side of lead ion adsorbed film Method, this method is by Kynoar (PVDF) and mesoporous SiO2Microballoon is blended, and then precipitates phase conversion method by solution Gained, comprises the following steps：
(1) the mesoporous SiO of amino functional is prepared2Microballoon：
N- lauroyl propylhomoserin sodium (Sar-Na) is dissolved in distilled water, HCl solution is then added dropwise, is stirred, it is then slow It is slow to add tetraethyl orthosilicate (TEOS) and 3- aminopropyl trimethoxysilanes (APTMS), stirring, then by reaction solution Stand, centrifuge out precipitation, then by washing of precipitate, drying, ethanol-ethanolamine solutions are extracted, then again through centrifugation, washing Be dried to obtain powdered SiO2Microballoon；
(2) casting solution is prepared：Mesoporous silicon oxide, lithium chloride (LiCl), the PVDF powder that step (1) is obtained are distributed to In DMF (DMF) or DMA (DMAc), casting film is made in stirring, vacuum defoamation Liquid；
(3) PVDF/SiO is prepared2Composite membrane：The casting solution that step (2) is obtained is poured on the glass plate of smooth pieces, with scraping Film rod striking film forming, is subsequently placed in solidification in distilled water and obtains PVDF/SiO2Composite membrane is the lead ion adsorbed film.
The present invention solves the problems, such as that the technical scheme of the product technology is：Design a kind of lead ion adsorbed film, it is characterised in that the film It is by Kynoar (PVDF) and mesoporous SiO2Microballoon is blended, and then precipitates phase inversion by solution and is made.It is mesoporous SiO2Prepared by microballoon and film formation is by preparation method defined of the present invention.
PVDF/SiO of the present invention2Composite membrane, its intermediary hole SiO2In fenestra, mesoporous SiO is effectively solved2Nano-particle Reunite, inconvenient problem with use, while effectively having played mesoporous SiO2Characterization of adsorption.
PVDF/SiO of the present invention2Composite membrane, using the mesoporous SiO of copolycondensation method one-step synthesis amino functional2, amino work( Energy group is dispersed in mesoporous SiO2Surface and hole surface, improve mesoporous SiO2The ability of adsorpting lead ion.
The outstanding advantages of the present invention are by mesoporous SiO2Microballoon is fixed in fenestra, so that mesoporous SiO2Microballoon is adsorbed to lead ion The big characteristic of amount and the load capacity of perforated membrane are big, and adsorption-desorption lead ion speed is fast, is ideally combined the advantages of easy to use one Rise, be a kind of new separation membrane.
PVDF/SiO of the present invention2The preparation method of composite membrane is simple, can be carried out under atmospheric pressure state, reagent used is Conventional reagent, device therefor is simple, it is easy to industrializing implementation.
Embodiment
The present invention is further discussed below with reference to embodiment：
The present invention is a kind of lead ion seperation film and preparation method thereof.The film is as film forming master from Kynoar (PVDF) Material is wanted, by mesoporous SiO2Microballoon is fixed in fenestra and is made.Its design principle is to prepare the mesoporous SiO of amino functional first2 Microballoon, then it is blended with PVDF, and precipitating phase inversion by solution is prepared into PVDF/SiO2Flat Membrane.Due to PVDF With mesoporous SiO2Microballoon is incompatible, is separated in film forming procedure, causes mesoporous SiO2Microballoon is located at gained PVDF/SiO2It is flat The fenestra of plate film.Therefore, product of the invention can be by the SiO of adjusting film2Micro-ball load amount and membrane pore structure, so as to adjust Lead ion adsorption function, is a kind of new lead ion separation membrane material.
PVDF/SiO of the present invention2In composite membrane preparation process, resulting film is cleaned repeatedly with deionized water, is removed Pore-foaming agent.
Although method of the present invention preferentially selects Kynoar (PVDF) Flat Membrane, it is equally applicable to other forms Film, including tubular membrane, the other forms such as hollow-fibre membrane, and prepare with this corresponding PVDF/SiO2Composite membrane.
