A macroscopic and microscopic study of the role of iron oxides in the removal of contaminants

Chemical compounds originated by anthropogenic activities reach the environment and interact with the mineral and organic fractions of the soil, where they suffer different reactions which will affect their final destination in the environment. In order to understand and predict the behaviour of the...
