abstract = {By using dialysis equilibrium experiments, the sorption of
a branched nonylphenol isomer
[4-(1-ethyl-1,3-dimethylpentyl)-phenol] (NP111) on various
humic acids (HAs) isolated from river sediments and two
reference HAs was studied. The HAs were characterized by
solid-state (13)C direct polarization/magic angle spinning
nuclear magnetic resonance ((13)C DP/MAS NMR) spectroscopy.
Sorption isotherms of NP111 on HAs were described by a
linear model. The organic carbon-normalized sorption
coefficient (K(OC)) ranged from 2.3×10(3) to
1.5×10(4)Lkg(-1). Interestingly, a clear correlation
between K(OC) value and alkyl C content was observed,
indicating that the aliphaticity of HAs markedly dominates
the sorption of NP111. These new mechanistic insights about
the NP111 sorption indicate that the fate of nonylphenols in
soil or sediment depends not only on the content of HA, but
also on its structural composition.},
