I am working on phytoremediation of industrial wastewater by aquatic plants; I want to apply degradation kinetics for physico-chemical and heavy metals from wastewater by the phytormediation process.
Which kinetic equation will be most suitable on which kind of parameters. Kindly provide the valuable suggestion regarding this.
Thanks
This removal is more complex - remember to include/check the possibility the adsorption of the metal ions on the plant. Secondly the uptake of the ions by the plant.

Jodengra, I concur with Grzegorz thoughts. Treatment wetlands are very complex and I assume you mean removal when you say degradation. Heavy metals can adsorb onto soil, plants roots and stay there, onto the microbial biofilm that grows on roots, some might be taken up by plants, some volatilize. I would go to a very good book "Treatment Wetlands" by Kadlek and Wallace, you will find what you need there.
This book is excelent and provides the equations that can be used on similar cases: http://www.editoraufv.com.br/produto/2083484/disposicao-de-aguas-residuarias-no-solo
It is in Portuguese because was prepared based on Brazilian´s wetlands case studies and designs implementation, but can be easily translated. Maybe there is a digital version of it. Regards and Good Luck. GT
I would start with a small artificial/controlled plot and plant Typha. It grows quickly, has very good nutrient uptake and will extract heavy metals as well. One must be careful though as Typha can spread quickly, and could be a potential fire hazard if the artificial bed dries out over the winter. It is a simple affair to harvest and extract the light and heavy metals from the plants to see the extraction rates and best dosing. You can up-size when you determine your overall needs. We spray irrigate and treat about 2,000,000 U.S. gallons of landfill leachate onto a closed, lined landfill cell, however we are using various types of trees and wild grasses to remove contaminants.
Try Typha in a small controlled test plot. Easy to harvest and determine the nutrient and metals uptake. The plots can be upsized to suit your needs. Certain trees can also be used if you have enough rooting depth in the test plot.
