Morphology
The noun phrase is directly compositional: 'activated' describes a charcoal that has been made more reactive or treated, so a learner who knows both words can infer it refers to a processed form of charcoal. This pattern (e.g. Spanish 'carbón activado', French 'charbon activé') is cross-linguistically common and would allow a B1 learner to understand the general meaning (a treated charcoal used for purification/adsorption).
Etymology
Activated charcoal The name activated charcoal comes from activated, meaning treated to work better, and charcoal, which is burnt wood. This treated charcoal is full of tiny holes like a dark sponge, so it can 'soak up' poisons and impurities, which is why doctors and water filters use it.
