I want to set up a pot experiment of which phytoremediation techniques should be used as to remove metals. So, which plant I should use or who are the most effective accumulators.
Water hyacinth (Eicchornia crassipes) is a best candidate for phytoremediation of various hazardous chemicals as well as easy to maintain. Try with that. Cheers.
Manavi Ekanayake Water hyacinth may not be a great choice if Tamjid Us Sakib is trying to remediate a dryland farm soil as it grows in waterways and ponds. He lists soil science and soil chemistry as some of his interests rather than wetlands.
There are phytoaccumulators from all over the world, depending on the elements of interest. For example Ni is described in this article:Article Nickel hyperaccumulation mechanisms: a review on the current...
There is even a Wikipedia page on hyperaccumulators: https://en.wikipedia.org/wiki/Hyperaccumulators_table_–_3
Perhaps a google scholar search would help you to narrow down the elements and species that is most appropriate for your project.
water hyacinth, water lettuce, and Azolla pinnata can be used for phytoremediation of wastewater. these species is highly effective for the treatment of any kind of wastewater.
Also, water hyacinth ( Eichhornia crassipes ), the free-floating perennial aquatic plant is good plant for heavy metals accumulation such as Cadmium, Chromium and Zink.
