Adsorption is the adhesion of particles or molecules onto a surface (e.g., activated carbon adsorbing impurities), while absorption is the uptake of a substance into the bulk of a material (e.g., a sponge absorbing water). These processes are critical in catalysis, purification, and separation techniques. Understanding the distinction helps optimize industrial processes like gas scrubbing and water treatment.
