Anthropogenic carbon dioxide (CO2) emission is the main reason for abnormal increased in CO2 concentration in our atmosphere since the sixteenth century,leading to the rise of global temperature [1].CO2 capture from flue gas of fossil fuel combustion is a most important and pressing challenge [2].Absorption and stripping using aqueous alkanol amines is the process because the theory and practice of this process have well documented [3-4].Although the above absorbents of CO2 have high reactivity and canying capacity of CO2,they are typically corrosive [5] and probable that being environmentally malign [6].
