Abstract

Pollution of water resources is one of the main factors that reduces the availability of fresh water and increases the use of advanced treatment techniques. This paper discusses the use of an adsorbent material produced through fast pyrolysis and chemical activation with sodium hydroxide (activated charcoal) and without thermal treatment (in natura) from the fruits of Casuarina equisetifolia for advanced water treatment and oily wastewater by adsorption, providing an effluent suitable to final disposal ou reuse. The adsorption isotherms were obtained by varying the temperature and the mass of bioadsorbent, and comparing its adsorptive capacity with other vegetal adsorbents, among them a commercial product. It was also developed a statistical analysis for process optimization. The bioadsorbent in natura showed greater adsorption capacity than the activated carbon, under the same experimental conditions, revealing that it has a good potential to be used as an adsorbent for water and wastewater treatment by adsorption.
