SOBRINHO, Oswaldo Palma Lopes et al. A proposal for a trial lesson using babassu mesocarp (orbignya speciosa) in the removal of methylene blue from aqueous solutions. Educ. quím [online]. 2015, vol.26, n.4, pp.314-318. ISSN 0187-893X. https://doi.org/10.1016/j.eq.2014.12.001.
The development of ecological awareness in different layers and sectors of society in Latin America involving Education, which may contribute to the formation of a creative economy, related to experimental practices with concern for environmental issues. The objective of this research was to develop an experimental low cost and easy implementation which was used biomass babassu (babassu mesocarp) as biosorbent in the removal of methylene blue dye from aqueous solutions. The babassu mesocarp showed good sorption capacity were used since small amounts of biosorbents in the removal of dye. It was found that there is a proportional relation between the amount of the biosorbent and dye concentration, at least in dilute solutions. We could realize the importance of washing step during the preparation of biosorbent. It is at this stage that are removed water soluble substances which can enhance the effluents of organic matter. The experiment also promote the concept of environmental sustainability and reuse of waste, as well as enrich the practical and settings chemical sorption, bioremediation, sorbent, biomass, intermolecular forces, solubility, polarity and biosorbent. Also, be keen curiosity of students, awakening them to the importance of research in chemistry
