| 摘 要： | 研究了多环芳烃菲(PHEs)在4种不同粒径的含水层砂土中的吸附规律及其吸附速率线性方程,探讨了离子强度和pH等因素对菲吸附的影响。结果表明:总体来说砂土对菲的吸附量都很小;直径在0.15～0.25mm范围内的砂土对菲的吸附效果最好、速率最快;含水层的离子强度越大、pH越大,砂土对菲的吸附量越小。

| Abstract: | This paper studied the adsorption rule and adsorption rate linear equations of PHEs in four different size sands of the aquifer.Influence of ionic strength as well as pH and other factors on the adsorption of PHEs were also discussed.Results showed that the adsorption abilities of sands on PHEs are very small,sands with the diameter between 0.15mm and 0.25mm have the best adsorption effect with the fastest adsorption rate,as well as the greater the ionic strength and pH are,the smaller the adsorption on PHEs are. |
