Artigo:

Dyes and pigments are widely used in the textile, food, paper and cosmetics industries, and for this reason a huge amount of effluent is generated in these segments. Without proper treatment, the discharge of these effluents is associated with several environmental problems and has been a major concern over the years. Thus, this study evaluated a type of brown macroalgae (Fucus vesiculosus) and its modification with sodium hydroxide for methylene blue biosorption. The biosorbent characterization revealed as major components carbon and oxygen, lipids and proteins were also observed. For both biosorbent (unmodified and modified) the Langmuir model presented the best fit for the experimental data, revealing a maximum adsorption capacity of 698.47 mg·g-1 and 818.16 mg·g-1 for unmodified and modified biosorbent.
