A new material of cotton fiber/Al 2 O 3 /SiPy + Cl − , COTALPy, was prepared containing on its surface the polymer silsesquioxane 3‐ n ‐propylpyridinium chloride strongly adhered. This new composite based on long fibers of natural cotton is chemically stable and had its adsorption properties studied. The COTALPy presented a maximum ionic exchange capacity of 0.85 mmol g −1 by potentiometric titulation. The adsorption isotherms of CuCl 2 , ZnCl 2 , CdCl 2 , NiCl 2 , and FeCl 2 in ethanol solutions were determined for each metal. The adsorption process was studied and data compared with the Langmuir model. The maximum adsorption capacities (in mmol g −1 ) were: CuCl 2 = 0.20, ZnCl 2 = 0.18, CdCl 2 = 0.35, NiCl 2 = 0.22, and FeCl 2 = 0.68. Real samples of fuel ethanol were eluted through a column containing the COTALPy, and it presented high‐practical potential for removal of metallic ions. © 2011 Wiley Periodicals, Inc.
