Within the new technologies for removing contaminants from industrial effluents the biosorption processes have great potential, characterized by the use of inexpensive, non-toxic and biodegradable materials,. The term "biosorption" is used to refer to the uptake of contaminants that performs a biomass (dead or alive), through physicochemical adsorption, complexation, ion exchange or steric entrapment. There are many antecedents on the use of aquatic plants, algae and microbial biomass for wastewater treatment, as they absorb or adsorb nutrients, heavy metals and various pollutants. This work presents the results obtained in experiments using a batch stirred tank reactor with biomass of macrophytes from the type Lemnaceas, native to the Pampas, in order to use the parameters thus obtained in the design of reactors for treatment and recovery liquid industrial effluents.
