采用3种大型海藻—裙带菜、海黍子、马尾藻对重金属镍离子进行吸附,研究了溶液的pH值对Ni2+ 吸附特性的影响。得到最佳pH值,发现了相同浓度、不同pH值的溶液吸附镍离子后pH值的变化规律及不同浓度、相同pH值的溶液吸附镍离子后pH值得变化规律,为进一步探讨海藻吸附重金属的吸附机理提供了依据。
Abstract：The effect of pH on nickel adsorption by three marine algae-Undaria pinnatifida, Sargassum kjellmanum and Sargassum natans has been studied in this paper. Nickel adsorption is strongly dependent on pH and has a wide range of proper pH of 47. The changing rules of pH in solution after adsorption at the same concentration, different initial pH and at the same initial pH, different concentrations have been discovered. This has provided the basis for discussing the adsorption mechanism farther.
