摘要

In this paper the sorption behavior of DBSA on two different types of soil humic acids (HAs) was investigated and the mechanisms of their interactions were further discussed. HAs were extracted and isolated from two representative soils, i.e., Mollisol soil and Alluvial soil. HAs sorbed by DBSA were measured by UV-vis and studied using the batch equilibrium method. Furthermore, the sorption complexes were analyzed by the means of elemental analysis, micro-Fourier transform infrared spectroscopy (FTIR), solid-state 13C nuclear magnetic resonance (NMR) spectroscopy and electron spin resonance spectra (ESR) in order to probe the sorption mechanisms. The sorption kinetics were relatively slow and the sorption equilibrium could be reached within 48 h. The sorption capacity of the Alluvial soil HA (AHA) was greater than that of the Mollisol soil HA (MHA). The maximum DBSA adsorption capacity on the AHA and the MHA was 115.01 mg/g and 112.17 mg/g, respectively.
