phenols [210, 211] fatty acids [212] and basic nitrogen compounds such benzoquinolines [213] from different matrices. A non-aqueous ion-exchange method has been
used for the separation of sediments into acid, base and neutral concentrates [214].
The acid concentrate obtained in this way can be separated into subfractions using
