The end treatment technologies for low-carbon fatty amines(LCFAs)are mainly divided into three types,including physical methods,chemical methods,and biological methods.Physical methods mainly include liquid-phase absorbing method,adsorption method,air stripping method,and membrane separation method;Chemical methods mainly include low-temperature plasma method,high-temperature catalytic oxidation method,photocatalytic oxidation method,microwave radiation method,and liquid-phase advanced oxidation method.Related mechanism,treatment efficiency,advantages and disadvantages of various methods are introduced.Research shows that although the removal methods for LCFAs are diverse,each one have certain limitations to varying degrees.Given the excellent water solubility of LCFAs,it is proposed that the combination of liquid phase absorption and advanced oxidation/biological methods will be a very promising technology for LCFAs treatment.Finally,prospects for the future governance direction of LCFAs are predicted.
