文法句型

verb + cationically

cationically + past participle

用法筆記

Specific to cleaning products where the active molecule is a cation (a quaternary ammonium compound, for example). Distinguish from sense 1, which covers general chemical behaviour of cations.

常見錯誤

❌The soap cleans anionically because it has a negative charge.
✅Most soaps clean anionically, but this disinfectant works cationically.
💡Standard soaps are typically anionic; cationic cleaners are a distinct category often used for disinfection and fabric softening.
