Abstract

In recent decades there has been an increase in the consumption of goods and services in all spheres of Brazilian society, which led to increased demand for industrial products, consequently increasing waste generation and these often with metals in their composition. As stipulated by the Federal Law Nº 9.605, the industry is responsible for the management of its waste, but this process is often costly and disposal of liquid portion of the waste generated sometimes happens in the common sewage system of the city. However, sewage systems were not prepared to manage industrial waste, so chemical compounds - like the metals - are not treated and eventually are released into water bodies, polluting them. Allied to conservation of natural resources and to reduce the costs for industrie's waste management, biosorption method has proven to be an attractive alternative from the economic and environmental point of view offers a low cost and is easily obtainable. In this research project will analyze the efficiency of yellow passion fruit (Passiflora edulis f flavicarpa.) as a biosorbent materials of metals: zinc, copper, nickel and lead. Whereas these metals are commonly found in cells; batteries; household items, and other objects that are part of day-to-day, and second FIGUEIREDO (2013), although these compounds are necessary to humans, high concentrations have a cumulative aspect in the body, which can cause problems for both nature and for human health. The choice of yellow passion fruit occurred for two main reasons: appropriate chemical composition for carrying out the work, low cost and easy to obtain. It is noteworthy that Brazil is the largest producer of passion fruit (IBGE 2007), and most of the production is directed to the juice production. This sector generates as waste peels and fruit seeds, which can cause environmental and economic problems, due to high fermentation and degradability resultant of its high humidity. Therefore the highlight of this work is the use of a solid waste, peel passion fruit, for treating industrial effluents. (AU)
