| 摘 要： | 本研究从竞争吸附系数的角度探讨了三种重金属共存时碱渣表面的吸附规律。研究显示,随着体系pH和初始浓度的升高,Cu2＋的竞争吸附系数呈下降趋势,Zn2＋、Cd2＋呈上升趋势;但是随着温度的升高Cu2＋竞争吸附系数呈现升高的趋势,Zn2＋、Cd2＋的竞争吸附系数则呈现减小的趋势。Zn2＋、Cd2＋呈现明显的协同吸附作用,而Zn2＋、Cd2＋与Cu2＋则呈现拮抗作用。

| Abstract: | This paper investigated the competitive Absorption effect of three heavy metal ions on alkaline sludge ,which was demonstrated by their competitive Absorption coefficients. Results show that the competitive Absorption coefficient of Cu2＋ decreases with the increase of pH and initial concentration ,while the coefficients of Zn2＋ and Cd2＋ exhibit the opposite trend. The coefficient of Cu2＋ increases with the increase of temperature,while the coefficients of Zn2＋ and Cd2＋ decrease.Moreover Zn2＋ and Cd2＋ have synergistic absorption effect on alkaline sludge, while definite antagonistic absorption effect among Cu2＋ ,Zn2＋ and Cd2＋ is also exhibited. |
