Abstract

BRES, P; CRESPO, D; RIZZO, P  and  LA ROSSA, R. Capacidad de las macrofitas Lemna minor y Eichhornia crassipes para eliminar el níquel. RIA. Rev. investig. agropecu. [online]. 2012, vol.38, n.2, pp.153-157. ISSN 1669-2314.

The aim of this work was to study the capacity of two macrophyte species, Lemna minor and Eichhornia crassipes to remove nickel. Four treatments were carried out for two weeks with each species: plants were either incubated with 0, 1, 3 and 6 mgl-1 de Ni. All treatments with both plants showed a decrease in Ni concentration over time. L. minor proved to be more efficient to remove the ion at the lowest concentration. At higher concentrations, however, no differences were observed between both species. The analysis of plant tissue showed that plants accumulated the metal at the three concentrations evaluated.
