| 英文摘要 | A comparative study was conducted to investigate the adsorption characteristics of phosphorus (p) on two soil samples collected from a typical subtropical reservoir and to reveal the possible influence of alternating exposure and inundation on the p adsorption onto soil in a water level fluctuation zone. short-term batch experiments were performed, and characterization methods, such as scanning electron microscopy (sem) and fourier transform infrared (ft-ir) spectroscopy, were also used. the p adsorption kinetics for both soils was best described by a pseudo-second order model (r-2 > 0.99). a modified langmuir model described the p adsorption on both samples well, and low temperature increased the risk of releasing soil p into the overlying water. low ph values were not conducive to the p adsorption process. it appeared that alternating exposure and inundation had no significant impact on the adsorption capacity of p onto soil from water level fluctuation zones in this research. ph, sem, and ft-ir analyses demonstrated that fe, al, and ca contained in the clay minerals of the soil played an important role in the adsorption of p onto soil from water level fluctuation zone. |
