Produção, caracterização e utilização do carvão ativado obtido dos caroços de Oenorcapus bataua mart. na adsorção de azul de metileno

Abstract

The increase in incorrect disposal of effluents in natural environments has contributed to the increase in cases of environmental pollution, especially with regard to the presence of dyes in aquatic environments. From this perspective, it is necessary to look for elimination strategies for these substances that are low cost and have a high efficiency rate. It is in this context that the production of activated carbon from alternative materials emerges as a solution to this problem. Thus, the present study aimed to evaluate the efficiency of activated carbon derived from patauá seeds (Oenorcapus Bataua) for the absorption of methylene blue dye in aqueous medium. The methodology used consisted of burning the patauá seeds at high temperatures, as if a physical activation were carried out. A methylene blue solution with a volume of 1000 ml was prepared. Shortly after, they were fractionated into concentrations of 5, 10 and 15 ppm. The results obtained in this study were promising, considering that the adsorption of methylene blue in aqueous medium was 72.45%, 80.97% and 89.99%. It is concluded that patuá seeds are an excellent alternative as adsorbent material due to their high adsorption rates.
