环境矿物界面反应动力学

环境矿物界面反应动力学主要探讨地表中各种有毒、有害离子或分子与矿物表面之间的反应速率与反应机制。矿物表面存在一组化学活性很强的表面功能基，当它们与环境中毒害物质发生作用时，会因其极性、荷电性和Lewis酸碱性不同而表现出不同的作用力和反应速率，进而控制有毒、有害物质在大气、水体和沉积物中的赋存形态，稳定性及迁移转化速率。本文简要介绍了环境矿物界面反应动力学理论，并给出几个应用实例。

The Kinetics of Interface Reaction of Environmental Minerals

The kinetics of interface reaction of environmental minerals is subjected to study the reaction rate of the toxic metal ions or hazard organic molecular on the mineral surfaces in earth surface environments and explore their interface reaction mechanism. On the mineral surfaces there exists a sort of functional groups that have very strong chemical activity. During the migration of the toxic metal ions or organic molecule on earth surface they would be reacted with the mineral surfaces and have different driving force and reaction rate for both of the surface functional groups and ions or molecule have different polarity, charge and Lewis acidity. These reactions process will forth control existing forms and stability of the toxic matter, as well as their migration and transformation in atmosphere, water system and sediments. This article gives a brief introduction about the kinetic theory of the interface reaction of environmental minerals and some application examples.
