cationbased
Cationbased is an adjective used in chemistry and related fields to describe systems, materials, or processes in which positively charged ions (cations) are central to the function or property being described. The term is not a formal, universally defined category, but rather a descriptive label applied to emphasize the role of cations, as opposed to anion-based or neutral systems.
In water treatment and analytical chemistry, cationbased approaches rely on cation exchange or selective binding of
Examples include cation-exchange resins used to remove specific metal ions, cationic polymers for gene delivery, and
Important considerations for cationbased systems include selectivity for target cations, charge density, hydration energy, stability under
