I want to contaminate the soils artificially . Initially , soils have 3 mg Fe per kg soil. How much Fe concentration is (mg per kg of soil) required?
How much Con do you want to obtain ? Just calculate the amount of Fe salt according to your desire trearments and mix with soil
Dear, my question is that. How much I have to add (mg per kg soil) to artificially contaminated the soil.
Foe example, Cd toxic tlevel in soil stars from 10 PPm. so whats about Fe.
Natural soils have large amounts of iron but not necessarily are contaminated or toxic to live beings. The amount of Iron in solution dependes on soil pH and red-ox potential. Fe (3+) precipitates readily at pH above 3,5 unless there are chelating agents in solution. Under reduce conditions Fe(3+) reduces to Fe (+2) and becomes more mobile.
