Chemical characterization dissolved organic carbon

Municipal landfill leachate typically contains dissolved organic carbon (DOC) concentrations up to several thousand (typically >1700 ppm), even in a landfill that is decades old (Christensen et al. 1998). More than 200 organic compounds have been identified in municipal landfill leachate (Paxe us 2000). Therefore, an effective chemical characterization of landfill leachate by numerous analytical techniques requires a previous isolation procedure in order to remove possible interferences. In our previous study, we tested the advantage of the ultrafiltration... 

Over 30 % of dissolved organic carbon (DOC) in surface water is classified under the category of humic substances (HUS). These are relatively high-molecular compounds with a complex structure which still remains to be clarified accurately. For this reason it is especially important to characterize HUS by determining their physico-chemical properties.
