Study Notes
Absorption and Adsorption
- Absorption is a process in which a substance is taken in by a cell or organism, whereas adsorption is a surface phenomenon where a substance binds to a surface.
Adsorption Characteristics
- The key characteristic of adsorption is the concentration of a substance at a surface or interface.
Enterosgel Intestinal Adsorbent
- The primary function of Enterosgel Intestinal Adsorbent is to absorb toxins and other harmful substances from the gut.
Absorption vs Adsorption
- Absorption involves the uptake of a substance into the bulk of a material, whereas adsorption involves the concentration of a substance at a surface.
Adsorption Mechanism
- The primary mechanism by which adsorption occurs in porous molecules is through van der Waals interactions or electrostatic forces.
Adsorbent Materials
- Activated carbon is a hard, granular, and porous adsorbent.
Hydrophilic and Hydrophobic Compounds
- Hydrophilic compounds are typically polar in nature, whereas hydrophobic compounds are typically non-polar in nature.
Adsorbent Surface Area
- The main requirement for adsorbents to have increased exposed surface area for adsorption is a high surface-to-volume ratio.
Functional Groups in Polymers
- Polar or non-polar functional groups are present in a porous polymer matrix in the class of compounds known as polymeric adsorbents.
Activated Alumina
- The primary reason for the use of activated alumina in adsorption is its high surface area and affinity for binding ions and molecules.
Adsorption Interactions
- The primary interactions responsible for adsorption in porous molecules are van der Waals interactions and electrostatic forces.
