The effects of pH and surface composition on Pb adsorption to natural freshwater biofilms

Article Abstract:

Natural surface coatings from Cayuga Lake, New York with components Fe oxide, Mn oxide, Chlorella vulgaris, and Leptothrix discophora cells are collected and studied for the adsorption of Pb in relation to a pH range of 5-8. The results are compared to the predicted results of a Kurbatov-based additive model, and graphed for Pb binding to the biofilm components at different pH levels.

Modeling oligotrophic biofilm formation and lead adsorption to biofilm components

Article Abstract:

Biofilm reactors have been used to investigate lead adsorption in aquatic environments because they allow analyses of the complex interactions of lead in complete biological systems. Herein, an integrated model describing the behavior of lead in oligotrophic freshwater aquatic environments is investigated with a laboratory biofilm reactor system. The results suggest that adsorption of lead to aquatic systems is much higher than has been previously reported.
