In this work, the aluminum surface was modified with different characteristics by anodizing and etching techniques. Two-type of modified surface aluminum of oxide film type and spike type were introduced as an aluminum substrate with various preparation conditions. Then, the modified surface aluminum was coated with a synthesized zeolite particle using silane as a coupling agent and became a composite adsorbent with 25–200 μm of layer thickness. The adsorption isotherms of the aluminum composites were investigated at 30°C.
