trapping

Trapping is a chemical process where molecules or particles are captured and held within a specific location or medium, preventing their movement or escape. This can occur naturally, such as pollutants or gases becoming confined within a porous material or a physical barrier. In industrial or scientific contexts, trapping is used to isolate, separate, or contain substances. It relies on physical or chemical interactions, like adsorption or confinement within a structure, to effectively hold the molecules in place. This process is essential in areas like filtration, pollution control, and chemical manufacturing.
