| Each type of material will move down the column at a different rate, depending on the its solubility and its tendency to be adsorbed. |
| In the open atmosphere many solid materials are covered by a layer of molecules adsorbed from the gas. |
| Thus, the adsorption and affinity of each protein studied should be quite different when they are adsorbed on a hydrophobic surface. |
| Then ammonium acetate solution was added to replace the adsorbed sodium with ammonium ions. |
| These species may be metal ions, surface defects, or adsorbed molecules or ions with one or more unpaired electrons. |
| He experimented by exposing paraffin wax to crushed Salvia leaves and found the solid wax readily adsorbed the volatile terpenes from the air. |
