Aquatic plants were screened to evaluate their ability to adsorb dissolved
metals. The plants screened included those that are naturally immobilized
(attached algae and rooted plants) and those that could be easily
separated from suspension (filamentous microalgae, macroalgae, and
floating plants). Two plants were observed to have high adsorption
capabilities (mg metal/kg of biomass) for cadmium (Cd) and zinc (Zn)
removal: one blue green filamentous alga of the genus Phormidium and
one aquatic rooted plant, water milfoil (Myriophyllum spicatum). These
plants could also reduce the residual metal concentration to 0.1 mg/L or
less. Both plants also exhibited high specific adsorption for other metals
(Pb, Ni, and Cu) both individually and in combination. Metal concentrations
were analyzed with an atomic absorption spectrophotometer (AAS).
