With the growing industrial observed in recent decades, the disposal of this wastewater industry has become more expressive, which consequently increases damage to the environment. As for pollution by metal ion, the problem is further aggravated, since these materials are not biodegradable, leading the bioaccumulation phenomenon - ease of sorption by plants and animals, reaching higher trophic levels - a factor that generates not only environmental damage, but also human health. In this context, a number of standards and national and international laws were created in order to minimize the presence of such materials in the middle, however, often the wastewater treatment with this composition is extremely costly, it is not common application. The biosorption then emerges as an affordable alternative, and that can still generate a return as much of the water - in the case of liquid waste - such as metallic materials, and possess no toxic waste, since the material can be recovered by desorption. Previous studies have shown that the shell of yellow passion fruit (Passiflora edulis f flavicarpa.) has the potential retention of metal ions most commonly released into the environment, such as: copper, zinc, lead, and nickel. These metals can be easily found in electroplating effluent, so this research project, renewing, is intended to evaluate the ability of the biossortiva passion fruit in real effluent. It is noteworthy that the adsorption mechanisms involve complex surface interactions between the ion and the solid adsorbent, requiring in-depth analysis on the material used. To this end, it established a partnership with Leibniz Institute for Interactive Materials (DWI) of the Technical University of North Rhine-Westphalia in Aachen (RWTH-Aachen), Germany. Through this partnership it is also possible to evaluate the desorption capacity of the material, and return to both industry biosorbent material used as the metal, enabling new uses. (AU)
