Chromium (VI) ion adsorption features of chitosan film and its chitosan/zeolite...
Batista, Anabelle C. L.; Villanueva, Emílio R.; Amorim, Rosa Valéria S.; Tavares, M. T.; Takaki, G. M. CamposThis research evaluated the importance of the adsorption properties of chitosan a chitosan/zeolite conjugate film for the removal of Cr(VI) ions from solutions in the 5–260 mg/L concentration range, when the pH was adjusted to 4.0 and 6.0. The uptake capacities of the films formed by chitosan and by the chitosan/zeolite conjugate were calculated by mass balance. The equilibrium isotherms were fitted to the Lang...
