A high internal surface area of activated alumina through the presence of pores (capillaries) is necessary to create adsorption sites. Activated alumina is the most widely used as adsorbent owing to the chemical properties of its surface and its ability to be formulated with well-defined pores defined as follows: • Macropores (diameter > 500 Å) to enhance diffusion into the pore system. • Mesopores (50 to 500 Å) to accommodate medium size molecules. • Micropores (< 50 Å) to accommodate small molecules like water.
