摘要

In this study, the bacterium was identified as Sphingomonas sp. XJ2 by means of microscopic examination, physiological, biochemical detection, and modern molecular biology technology. After acclimatization for several times, this bacterium has good performance in removing heavy metals and organic matter from seawater. Alginate immobilized cells has obvious holes on the surface and has big specific surface area, which are conducive to the adsorption of metal ions. Hydration heat of Pb~(2+) is small, and is most likely to drop out of ligand water then become exposed Pb~(2+); in addition, the ionic radius of Pb~(2+) and is very similar to the ball K+ and is adsorbed by the ball easily. FTIR and XPS study indicated that Pb (II) was complexed by C-H and C-O bonds. The concentration of Pb(II)of mine wastewater reach the first class of irrigation water quality standards after the first time of adsorption treatment, and reach the first class of fishery water quality standard after the second treatment.
