Title

Measurement and modeling of the efficiency of constructed wetlands in removing lead and zinc from neutral pH mine drainage

Author

Abstract

"Adsorption by organic matter, Fe hydroxide association, and sulfide precipitation are primary mechanisms for Pb and Zn removal from neutral pH mine drainage by constructed wetlands. A mathematical model was developed with the geochemical modeling tool PHREEQC to simulate the constructed wetland processes, including both kinetic and equilibrium aspects of the above removal mechanisms...This research provides a quantification method to evaluate removal mechanisms of a constructed wetland and is also a direct support for previous research on wetland removal mechanisms"--Abstract, leaf iii.
