The natural organic matter (NOM) from a large quantity (1000 L) of groundwater
from a Western Australian bore was isolated and separated into three polarity-based
fractions (hydrophobic, transphilic and hydrophilic) using an XAD-8/XAD-4 resin
fractionation method. These NOM fractions were separately treated by the magnetic
ion exchange (MIEX®) resin process to investigate the effect of the MIEX® process
on different organic polarity-based fractions. MIEX® was effective for targeting the
more non-polar (hydrophobic) and the intermediate polarity (transphilic) NOM, with
similar DOC removals observed for both the hydrophobic and transphilic fractions
from this groundwater. Analysis of the NOM samples before and after MIEX®
treatment by SEC-OCD showed that, for the hydrophobic fraction, organic matter
over a wide range of apparent molecular weights, was removed, with particularly
good removal of the high molecular weight material. Includes 18 references, table, figures.
