Aquatic phytoremendiation: Algae and aquatic plants for removal of toxic elements
Conference

OSTI ID:471971
A study to test several species of plants for heavy metal bioremoval is very briefly described. Adsorption isotherms were determined for cadmium, zinc, lead, nickel, and copper by measuring the amounts adsorbed by the biomass over a range of residual metal concentrations. Numerical results presented include adsorption characteristics of aquatic plants at pH 5 and specific adsorption of cadmium onto various biomass. The two best species were Phormidium, a blue-green alga, and Myriophyllum spicatum, water milfoil. The maximum metal ion absorbed the the minimal residual metal concentrations achieved allow estimation of the amount of biomass required to achieve a desired treatment level.
