Organic Acids in Leachate from Industrial Landfill

4 ORGANIC ACIDS IN LEACHATE FROM INDUSTRIAL LANDFILL 

Leachate samples from industrial landfills were analysed by LC-NMR and LC-thermospray (TSP)-MS with emphasis on organic acids [12], After removal of the neutral and basic components by pre-extraction with methylene chloride, 

On the other hand, the aromatic part of the on-flow NMR chromatogram is better resolved, both in the NMR chemical shift and along the chromatographic axis. As can be seen from the extracted rows of the NMR chromatogram
