大洋多金属结核浸出渣对含Cr^(6+)重金属废水的吸附研究

Experimental Study on Adsorption of Cr^(6+) Heavy Metal Ions with Oceanic Polymetallic Nodules

用新型固体工业废渣——大洋多金属结核浸出渣作为吸附剂,通过改变废水溶液pH值、吸附时间、溶液体积等条件,研究大洋多金属结核浸出渣对重金属离子Cr^(6+)吸附率的影响,从而确定了浸出渣作为吸附剂处理Cr^(6+)重金属废水的最佳吸附条件。

Experimental study with new solid industrial residues oceanic polymetallic nodules as adsorbent, by changing the pH value of wastewater solution, adsorption time, solution volume, the impact on adsorption rate of Cr^6＋ heavy metal ions with oceanic polymetallic nodules is studied. It is concluded that oceanic polymetallic nodules are as adsorbent of the best adsorption conditions.
