A process for the removal of metal ions from solution and means for effecting such removal are described. The process is based on the hydroponic growth of sunflowers, terrestrial turfgrasses and/or members of the family Brassicaceae in solutions containing one or more metal ions. Metal ions can be efficiently removed from solutions by passing these solutions through the root biomass of these terrestrial plants. Columns containing the root biomass are also part of the invention.

Procédé d'extraction d'ions métalliques à partir d'une solution, et dispositif permettant d'effectuer une telle extraction. Ce procédé se fonde sur la mise en croissance hydroponique de tournesols, de gazon et/ou de membres de la famille des brassicacées dans des solutions contenant un ou plusieurs ions métalliques. Les ions métalliques peuvent être efficacement enlevés des solutions par le passage de ces dernières à travers la biomasse des racines de ces plantes terrestres. Des colonnes contenant une telle biomasse sont également décrites.
