Crystalline rainbow

Crystals of dyes adsorbed on the surface of a biopolymer after a process of water purification. One of the most common and undesirable contaminants in the wastewater are the dyes. They are highly visible, stable and difficult to biodegrade. For removal of such contaminants are commonly used adsorption techniques.

Zinc crystals

Zinc crystals that have been adsorbed on the surface of an alginate gel after being subjected to a process of wastewater treatment. An important field of application of the alginates gels is the protection of the environment: alginate gels are used as adsorbents for the removal of heavy metals such as cadmium, zinc, lead, chromium and mercury in wastewater.
