摘要
研究重金属(Pb(Ⅱ)、Hg(Ⅱ))在中肋骨条藻(Skeletonema costatum)和链状亚历山大藻(Alexandrium catenella)细胞上的吸附和竞争吸附.实验结果表明,Pb(Ⅱ)、Hg(Ⅱ)在两海藻上竞争吸附时,Pb(Ⅱ)在海藻细胞表面的竞争吸附平衡快于Hg(Ⅱ).竞争吸附平衡时,藻细胞表面Hg(Ⅱ)对Pb(Ⅱ)的影响小于15%,Pb(Ⅱ)对Hg(Ⅱ)的影响大于50%.96h培养后,两金属竞争环境下的海藻细胞吸附(吸收)的重金属量明显高于单一重金属作用的海藻细胞的吸附(吸收)量.
The adsorption behaviors of Pb（ Ⅱ ） and Hg（ Ⅱ ） onto two algae （Skeletonema costatum and Alexandrium catenella ） with and without competing metal ions were examined in this study. In the system of all the two metals present, the interference of adsorption among the two metals is more significant： the balance time of Pb（ Ⅱ ） was faster than Hg（ Ⅱ ） while those in the competing systems. The influence efficiency of Hg（Ⅱ）to Pb（Ⅱ） was less than 15%, but Pb（Ⅱ） to Hg（Ⅱ） was more than 50%.After cultured 96h , The adsorption （uptake） of Pb and Hg onto two algae in competing system were obviously much more than those in single metal system.
