| Abstract: | A review on the application of liquid membrane extraction for environmental sample preparation is presented.The extraction techniques are generalized under three categories: the supported liquid membrane extraction(SLME) and microporous membrane liquid-liquid extraction(MMLLE) based on flat membrane and the liquid phase microextraction(HFLPME) based on hollow fiber membrane.The setting-up,principles and practical applications of these three categories for environmental sample preparation are introduced,respectively. |
