| Experimental data of the dependence of transmitted laser light intensity I of aqueous ADP solutions saturated at 303.15 K on feeding time t of three antisolvents (i.e. acetone, methanol and ethanol) are analyzed using mathematical equations based on two approaches. The first approach is based on exponential decrease in I with increasing t whereas the second one is based on the concept of adsorption of antisolvent molecules onto solvent and solute molecules. It was found that: (1) the latter approach is superior to the former one for explaining the observed dependence of transmitted laser-beam intensities of pure solvent and aqueous saturated ADP solutions, (2) the parameter A of the second approach provides better insight into the processes of adsorption of antisolvents in terms of the differential heat Qdiff of adsorption, and (3) the trends of changes in the values Qdiff for different antisolvents in water and aqueous solutions are associated with the dielectric constants of different antisolvents and are directly connected with the chemical constitution of the methanol, ethanol and acetone molecules |
