Neste estudo foram avaliados os comportamentos de equilíbrio e termodinâmico da adsorção de Azul de Metileno em quitina tratada via ultrassom. Foram construídas curvas de equilíbrio experimentais em diferentes temperaturas e, os dados foram ajustados a modelos da literatura. Os resultados mostraram que o modelo de Langmuir foi o mais adequado para representar os dados de equilíbrio. A máxima capacidade de adsorção foi de 26,7 mg g-1, obtida a 298 K. A adsorção foi espontânea, favorável e exotérmica.
