Application of Agricultural Waste from Main Brazilian Crops as Adsorbent for Wastewater Treatment




Adsorption is a powerful method for wastewater treatment. The adsorbent materials used are limited due
to the high cost of production and for their difficult regenerability. This work aims to show the importance
of reusing agricultural residues, transforming them into efficient adsorbent materials. Highlighting the
growing interest in the subject through bibliometric analysis and punctuating the main preparation
techniques with direction for specific characteristics desired in the materials, understood through the
main techniques of physical and chemical characterization. It will also be shown the economic and
quantitative relevance for Brazil of some agricultural crops of worldwide occurrence, as well as the
potential of transforming their residues into adsorbent materials for the treatment of effluents. Finally,
studies involving real effluents will be presented, corroborating the efficiency of these materials and the
possibility of future industrial applications. This set of information presents the reader with a valuable
amount of information about the real possibility of reusing agricultural solid waste as a powerful tool
in the treatment of urban and industrial effluents, thus increasing reuse and attacking two important
environmental problems.
