| 摘 要： | 研究了污泥颗粒对染料的吸附特性。并对pH以及离子强度对染料吸附的影响做出了评价。结果显示染料吸附经过 30min便达到了平衡 ;pH值是决定染料吸附的最重要的因素 ,随着 pH值的降低吸附量明显增大 ;染料吸附量随着离子强度的增加而减小。染料吸附可以用多层吸附等温线来描述。

| Abstract: | The dye adsorption characteristics of sludge particulates were studied. Major factors such as pH and ionic strength on dye adsorption were evaluated. An anionic dye was used as the adsorbate. The results show that dye adsorption is a fast process and can reach equilibrium in 30 min. The results also show that pH is the most important factor determining the dye adsorption. Decreasing pH can significantly increase the adsorption of the dye.It is found that the increase in the ionic strength decreases the dye adsorption density.Dye adsorption can be described by a multilayer adsorption isotherm curve. |
