The relationship between the number of molecules of the solution that was absorb against the weight of one unit to absorb the balanced concentration of a substance dissolved in the melt at the same temperature.
The relationship between the number of solute molecules are adsorbed. Compared with a unit weight of adsorbent at equilibrium concentration of solute in the solution at the same temperature.
The relationship between the number of molecules of the solute is adsorbed. Compared with the adsorbent with one weight concentration balance of solute in solution temperature, the same.
