The presence of chemical residues in aquatic environment can cause noticeable adverse physiological effects in humans and animals. In view of this, one needs methods to try to control its disposal, among these methods highlight the adsorption. The adsorption on solids is a phenomenon that focus on the surface of existing substances in liquids or gases. Due to the adsorption capacity of the derivatives of babassu (Orbignya phalerata, Mart.) and its abundance geographical took place this study was conducted with the purpose of transforming the coal into a potent babassu adsorbent useful for the treatment of industrial effluents, including pharmaceutical. The sieve analysis was performed and showed charcoal powder with a mean diameter of 500.475 mM, obtaining therefore a coarse powder. Potential adsorption system was elevated. According to the spectrophotometric reading, the initial concentration of methylene blue (3,85 mg/ml) was reduced to 0.106 g/ml in the system containing activated charcoal, thus resulting in a percentage adsorption equivalent to 97%. This study noted a keen perspective on the adsorption capacity of activated carbon from babassu front of the methodology employed. This material shows great potential for use in the manufacture of filters for the decontamination of industrial waste.
