天然海藻对Pb^(2+)的吸附作用的研究

The Research about the Absorption of Natural Varek to Pb^(2+)

铅存在于各种工业废水中,并对环境造成了极大的污染。我们用两种不同的方法处理海藻,其中包括:KMnO_4氧化法,水洗法。我们对这2种预处理过的海藻在水溶液中对Pb^(2+)的吸附行为进行了研究,并测定了时间和pH值对吸附平衡的影响。

Lead which can polute the environment seriously,is often present in different types of industrial effluents.We used the methods of potassinm permanganate oxidation and aqueous washing to deal with the varek.We studied the binding lead capacity in the aqueous solution of the two kinds of varek which had been pretreated,and also measured the required time and PH which can affect the absorption balance.
