A device, chemical, or substance used to remove arsenic from soil, water, or other materials.
From 'dearsenicate' (to remove arsenic) combined with the agent noun suffix '-or' (from Latin, indicating a person or thing that performs an action).
Environmental remediation scientists design dearsenicators to clean up contaminated sites—some use living plants that hyperaccumulate arsenic, essentially making plants into biological dearsenicators, which is way more elegant than industrial chemicals.
