Abstract
A new batch titration microcalorimeter has been used for estimation of thermodynamic properties in various investigated colloidal systems. As examples, we present enthalpic and kinetic data obtained from this calorimetric device for four different processes widely encountered in colloid science: (i) The dilution/micellization process of cationic gemini surfactants in aqueous solution. (ii) The hydration process of non ionic surfactants in organic solution, i.e. the mechanism of micellar solubilization of water in the aggregates. (iii) The complexation of calcium ions by polyacrylates sodium salts (PaNa). (iv) The adsorption phenomenon of PaNa molecules on the calcium carbonate surface.
