I have added Cadmium in the soil as three different concentration ranges (10, 50, 100 mg/kg) for my pot experiments. Can anyone suggest me the calculation for adding the chelating agents like EDTA, Citric Acid and Sodium sulphate to the contaminated soils?
Your help in this regards is highly appreciated.
Thank you.
Kind regards,
Anand.
You need to use a chemical speciation model to predict the free ion activities for different concentrations of the complexing species. You can download a free copy of Geochem-EZ. It is easy to use.
I suggest that you may have started the wrong way by adding such huge Cd concentrations.
In addition, the organic chelating agents will be subject to microbial decomposition
Dear Professor Paul Milham thank you for your kind reply and suggestions.
Sure Professor Paul Milham can I have your email ID? I want to discuss with you in detail.
It appears to me that quality of soils as well as cation exchange capacity, organic matter and metal content have to be analysed before starting this type of experiments.
Chelting agent can be added kn the basis of CEC of Soil and give altrantive wettjng and drying of Soil
