| 摘 要： | 采用批平衡法,研究了菲和Cu2+在黑垆土上的吸附及其交互影响。结果表明,菲和Cu2+在黑垆土上的吸附动力学曲线较好符合一级动力学方程,菲在黑垆土上的吸附主要通过分配作用,其吸附等温曲线符合线性Henry方程,Cu2+的存在抑制菲在黑垆土上的吸附;而Cu2+在黑垆土上的吸附主要通过表面吸附和专性吸附作用,其吸附等温曲线符合Freundlich方程,菲的存在促进了Cu2+的吸附;对菲和Cu2+来说,pH均是影响黑垆土吸附的主要因素,黑垆土对Cu2+的吸附量随着土壤溶液pH值的增加而增加,而对菲的吸附量随着pH增加而降低。

| Abstract: | The Interaction between phenanthrene(PHE) and Cu2+ sorption on dark loessial soil had been investigated using batch equilibrium sorption experimental method.The dynamics of the experimental results showed that the kinetic curves of both PHE and Cu2+ sorption on the dark loessial soils could be well described as pseudo-first-order kinetic equation.The sorption of polycyclic aromatic hydrocarbon(PAHs) on soil usually follows Henry linear isotherm,which was also observed for the sorption of PHE on the soil use... |
