The concentration and bonding of a substance to the surface of a second substance. The bonding is relatively weak and temporary, as for example the adsorption of nutrient ions to clay particles in a soil. The materials in the soil that are capable of adsorbing are known collectively as the adsorption complex. The amount of a chemical species taken up by the adsorption complex at a given temperature may be plotted against the concentration of that species in the co‐existing aqueous solution. The resulting graph is called an adsorption isotherm (McBride, 1994, p. 344–345).
