This study examined the potential for adsorption of methylene blue, in solution of 50 mg.L-1, by banana fiber spray, to 2 g/L of solution. We carried out variations in temperature and pH of the solution. The results indicate that it is possible to use the banana fiber as adsorbent methylene blue in ambient temperature and alkaline pH values with high efficiency. The FT-IR spectrum showed the presence of carboxylic acid and hydroxyl groups on the fiber. Such groups are capable of forming hydrogen bonds with methylene blue and removing it from the aqueous solution. It was concluded that for the conditions tested, the best temperature for adsorption was 25 °C and pH to better efficiency of better temperature was 11.
