Removal of Nickle ion from Mariculture Seawater with Marine Microorganism

摘要

This study use purely bacteria on suitable condition, eliminate other bacteria come in life-form bacteria. Through the orthogonal experiment obtains the optimum condition of sodium alginate fossilization Sphingomonas strain pellet to nickel bioremediation, and discusses the influence of single factor to the sodium alginate fossilization Sphingomonas strain pellet to nickel adsorption, including the time, the temperature, pH, the initial adsorbent density, the speed of the shaker, the absorbent which the different periods of growth bacterium does, coexistent ion, desorption. From the research, we know the maximum adsorption rate to nickel is about 85%. Dynamics research indicated that in the several methods of the sodium alginate of nickel, the methods of embedded micro-organisms embodies much advantages,as operating easily, effecting clearly, less pollution, costing low, etc.
