Effect of structural composition of humic acids on the sorption of a branched nonylphenol isomer
Effect of structural composition of humic acids on the sorption of a branched nonylphenol isomer
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/m...

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. |
