Modified montmorillonite in photo-fenton and adsorption processes
Nowadays environmental pollution is one of the major and more urgent problems to be resolved in the world. In particular, water contamination affects most of the planet being the situation more dramatic in the less developed countries. All the human activities from agriculture to the fabrication of...

Nowadays environmental pollution is one of the major and more urgent problems to be resolved in the world. In particular, water contamination affects most of the planet being the situation more dramatic in the less developed countries. All the human activities from agriculture to the fabrication of sophisticated electronic equipment need water, generating enormous amounts of effluents that should be purified before being discharge to the environment. Biological water treatment is without doubts the most popular in the entire world because it is versatile, cheap and can be used in big or small cities and for several industries. However, human activity generates wastewaters containing soluble metals and/or synthetic organic compounds that are non-biodegradable or, unlike natural occurring compounds, extremely resistant to biodegradation by native microorganisms (Ali, 2010).
