Abstract

The removal of nitrate from aqueous solutions of a synthetic medium was examined using two different aquatic plants, such as Hydrocharis dubia and Salvinia sp. The selected macrophytes were incubated in the laboratory in the container containing a previously prepared soultion of NH4NO3. Hydrocharis dubia reduced the nitrate level to 60.4% in a synthetic medium containing 100mg/L of nitrate. The efficiency of nitrate removal was further increased 78% with initial nitrate concentration of 300mg/L.
