The Influence of co-existing ions on adsorbs in the aqueous phase Pb~(2+) by Bacillus mucilayinosus

摘要

There are many factor influences on adsorption-flotation results to Pb~(2+) among, in the solution. The effect of co-existing alkaline-earth metals ions was examined by using Bacillus mucilayinosus as the absorbent on the condition of different pH value, the coexistence ion amount used as well as in tri-, four-, five-, six-coexistent ion systems, to absorbed water solution in Pb~(2+) ion. The adsorption the biological surface zeta - the potential shift, indicated the Bacillus mucilayinosus to the Pb~(2+) adsorption process in, the electrostatic attraction occupies the leadership, but in the multi-dimensional coexistence adsorption system, has the competition adsorption and the ionic exchange.
