Acesso em:.https://repositorio.ufpa.br/handle/2011/13952The formation of solid waste has become a great challenge for the environment preservation due to the lifestyle adopted by modern society, which seeks for practicality and immediacy, and by that, new products are released, and waste formation is increased. The decomposition of waste from various sources creates a dark liquid denominated “slurry”, which presents high concentration of organic and inorganic compounds. This study aimed to evaluate the concentrations of Cd, Cu, Cr, Mn, Ni, Pb, and Zn on the ground and percolated liquid produced at the solid waste decomposition site in the metropolitan region of Belém/Pará/Brazil. Fly ashes of mineral coal were used to produce a low-cost zeolitic material, for removing copper, zinc, cadmium, and chrome, which are present at the percolated liquid of the Aurá landfill. The zeolites synthesized by alkaline fusion (ZSH and ZSJ), and without alkaline fusion (ZSD, ZSG, ZSK, ZSO), were characterized by different techniques, such as X-ray fluorescenc espectrometry, X-ray diffraction, and Scanning Electron Microscopy. The treatment adsorption efficiency of using adsorbent zeolitic material demonstrated viability to be used as an adsorvent agent for the adsorption of metals present at the leachate produced by landfills.Acesso AbertoAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Aterro sanitárioCinza volanteZeólitaAdsorçãoMetais tóxicosSanitary LandfillFly ashZeolitaAdsorptionMetalsTeseCNPQ::ENGENHARIAS::ENGENHARIA SANITARIA::SANEAMENTO BASICO::RESIDUOS SOLIDOS, DOMESTICOS E INDUSTRIAISMEIO AMBIENTE E ENERGIAUSO E TRANSFORMAÇÃO DE RECURSOS NATURAIS
