According to this theory, the Gibb's free energy of mixing ([DELTA][G.sub.m]) for a ternary system is given as
The standard Gibb's free energy (IG0) values for natural red and basic blue were observed as negative.
Free energy is measured in kilojoules per mole, also called Gibb's free energy. The negative values of free energy change show that the solute is more concentrated on the adsorbent than in the bulk solution; that is, the system has reached equilibrium [25].
Crowding conditions caused an increase of the main [T.sub.m] [less than or equal to] 2[degrees]C and a decrease in the Gibb's free energy of maximally 4 kcal/mol.
