摘要

In this study, calcium alginate immobilized bacillus subtilis body was used as an adsorbent for the aim of adsorpting Cu( II) ions form the aqueous solutions, On sutiable condition, this study use purely bacteria eliminate other bacteria come in life-form bacteria .Through the orthogonal experiment obtains the optimum condition of sodium alginate fossilization bacillus subtilus pellet to the Cu( II) adsorption, The biosorption efficiency was strongly influenced by the pH and the initial concentration ofthe Cu( II) aqueous solutions. We also discusses the influence of single factor to the sodium alginate fossilization bacillus subtilus pellet to the Cu(II) adsorption ,which included pH, contact time, temperature, initial metal ion concentrations and ionic strength in the adsorption process. The adsorption of the adsorbent on Cu( II) is related to its concentration . From the research,we know the maximum adsorption rate to the Cu(II) is about 83.2%. Using different model to analyse data. The sorption process follows pseudo-second-order kinetics very well,and the correlation coefficients R all reached to 0.9, and the rate constant of this kinetics model for the adsorption processes, k.2, increased with the increasing temperatures. The isothermal data could be well described by the Langmuir adsorption isothermal equations. The experimental results showed that heavy metals could be eficciently accumulated by the immobilized bacteria.
