Imidazole ionic liquids wide application,stable,both ionic and organic characteristics, after the current into the environment, the water particles is their transformation processes important medium to explore the imidazole ionic liquid migration in the aquatic environment-conversion behavior, provide a valid basis for the management and use of ionic liquids. This paper studies the 1-butyl-3-methylimidazolium chloride([BMIM]Cl) adsorbed on the surface of the water particles,absorption,distribution and other migration and transformation mechanism of ion exchange, using typical materials such as activated carbon,montmorillonite,humus,1-octanol and other single factor research, access to transport and transformation kinetics equation to investigate the influence of temperature,concentration,organic matter content and other factors on the migration and conversion, and comprehensive information on all aspects of the establishment of the mathematical model and solve the equations, the main contents as follows: 1. [BMIM]Cl adsorption behavior research on particulate matterFirst, water and suspended particles of activated carbon as [BMIM]Cl were studied in the adsorption behavior on its surface, and secondly, as a body of water with suspended particles of montmorillonite [BMIM]Cl ion exchange behavior on which were studied by scanning electron microscopy SEM,XRD microstructure of activated carbon, montmorillonite were characterized through the ICP measured cation exchange capacity of montmorillonite which, by changing the reaction conditions, the reaction can be drawn from the desired equilibrium time, the optimum amount the optimum temperature for the above parameters available for data processing, derived particulate matter on [BMIM]Cl adsorption isotherm equation, reaction order and Gibbs then identify the ionic liquid adsorption from solution onto particles spontaneously process, activation energy, etc., to provide data support for mathematical modeling, and finally can be drawn [BMIM]Cl adsorption on the surface of the particles, the ion exchange capacity and [BMIM]Cl relationship between the equilibrium concentration of water. 2. [BMIM]Cl assigned role in the particulate matterInquiry [BMIM]Cl assigned the role of the water particles, measured [BMIM]Cl octanol direct assay-water partition coefficient through data processing to give the corresponding 1-octanol-water partition coefficient of organic matter distribution standardized coefficient and partition coefficient, Germany Jena MULTIN/C3000 Total organic Carbon analyzer detector analyzes solid organic matter Total organic Carbon(TOC) content for the final establishment of ionic liquid on the role of particulate matter distribution in the amount of ionic liquid liquid phase equilibrium relationship between the concentration pave the way. 3. [BMIM] Cl simulation study of migration behavior in natural waterNatural water particles composed mainly of soil ions and humus, which humus accounts for about 80% of the present study was to particulate matter humus mimic natural water bodies, by SEM,XRD on morphology humus was analyzed by changing the reaction conditions, can be drawn aggregate balance of time,the optimum amount of humus,the optimum reaction temperature and other conditions to explore [BMIM]Cl on migration behavior of particulate matter by [BMIM]Cl adsorption on the surface of particulate matter, cation exchange capacity and the allocation of roles and the relationship between the amount of [BMIM]Cl in simulated natural water humus accumulation and total solution [BMIM]Cl equilibrium concentration obtained [BMIM]Cl mathematical model of migration behavior in simulated natural water bodies.
