Abstract：Molecular weight(MW) distributions of organics in the Bei Shenshu landfill leachate and their permeation from membranes were determined and studied by absorption spectrum, and the removal rates of organics with various molecular weight were measured. A new FTIR preparation method of wastewater sample used in the determination of landfill leachate was proposed in the present paper. The results showed that the aromatics in landfill leachate were mainly related to the the organics with MW＜2 500, whereas the distribution of total organics was dispersal comparatively. The removal rates of various humic compounds and oils in landfill leachate were estimated in accordance with the change in FTIR absorbance of permeation from membranes at three characteristic wave numbers 2 930, 2 960 and 3 030 cm-1, indicating that the defined membrane treatment process can removed organics with relevant MW fractions effectively.
