چکیده
|
In this work, a new thermodynamic model based on the perturbation theory is presented. a new hard spheres equation of state as a reference term is applied to correlate the activity coefficient of amino acids and peptides in binary aqueous solutions. the new hard sphere equation of state has been recently proposed by dehghani and modarress [11] and has been applied for different theories and showed excellent capability. in this model dipole-dipole and lennard-jones interactions are considered. the results have been compared with similar models and it is shown that application of the new hard spheres equation of state has caused an improvement in the results of perturbation model.
