Definition
'Adsorptive' describes the property of a material to cause adsorption, meaning it attracts and holds molecules of a gas, liquid, or dissolved solid to its surface. It emphasizes the ability to cause adsorption. It's about the capacity to attract and hold, not just the state of being adsorbed. Unlike 'adsorbent' (the material), this describes the *quality* of attracting. It is a more descriptive adjective.
