| 摘 要： | 采用不同浓度水平壬基酚(NP)的颗粒物对菲的吸附行为进行等温吸附实验,并使用位点能量分布分析吸附态NP对菲吸附的影响机理,结果表明,菲在低浓度水平有机质天然水体颗粒物、去除有机质的水体颗粒物和高岭土颗粒物上的吸附均较符合Freundlich模型,亲水界面上菲的吸附位点能量较低,低浓度吸附态NP存在时,降低了吸附位点的数量,对菲在颗粒物亲水界面上的吸附产生一定抑制作用,但较高浓度的NP存在时,则可为菲的吸附提供新的低能量位点,从而促进菲的吸附.

| Abstract: | To investigate the effect of different levels of sorbed nonylphenol(NP)on sorption of phenanthrene onto hydrophilic solid phase. Pre-sorption method was done to gain the particles with different levels of sorbed NP, and then sorption isotherm experiment of phenanthrene was conducted using the batch experiment method, while site energy distribution analysis was done to indicate the change of site energy distribution of phenanthrene on different particles. It was found that phenanthrene sorption on the low or... |
