Title: adsorption capacity Long Title: IUPAC Gold Book - adsorption capacity DOI: 10.1351/goldbook.A00156 Status: current Definition For strongly adsorbed solutes of limited solubility, the value of the amount of adsorbed substance reached in a saturated solution is called the adsorption capacity of the adsorbent for a specific solute; its value depends also, in general, on the nature and, in the case of more than two components, on the relative composition of the bulk liquid.
