<Absorption (chemistry)> takes a <chemical substance> into a material's bulk, as when <carbon dioxide> dissolves in <water>. <Adsorption> instead concerns accumulation at a boundary. Bulk uptake and interfacial accumulation can coexist; total uptake alone does not separate their contributions. This use of absorption concerns material uptake, whereas <absorbance> describes attenuation of <electromagnetic radiation>.
