Phytoextraction

1999, Rufus L. Chaney, Yin-Ming Li, Sally L. Brown, Faye A. Homer, Minnie Malik, J. Scott Angle, Alan J. M. Baker, Roger D. Reeves, Mel Chin, Chapter 7: Improving Metal Hyperaccumulator Wild Plants to Develop Commercial Phytoextraction Systems: Approaches and Progress, Norman Terry, Gary S. Banuelos (editors), Phytoremediation of Contaminated Soil and Water, page 151, Phytoextraction is fundamentally an agricultural technology. Connecting this agricultural production system to metal recovery technologies will be a challenge for researchers and managers of phytoextraction enterprises.

The success of phytoextraction depends on two components, the contaminated soil and the plant species.

Changes in the polarity of eletrodes during the process can avoid fixed redistribution of heavy metals and soil pH values that are associated with different rates of plant biomass and phytoextractions to the proximity to electrodes.
