“…Adding Equations (9) and (15) which refer to the changes of mixing entropy and enthalpy respectively and using Equation (1), there is obtained the relation for free mixing energy: [24] DG M ¼ kTfn 1 ln n 1 þ n 2 ln n 2 þ n 1 n 2 v 1 g ½17…”

“…However, the problem of temperature influence on the polymer conformation both unadsorbed in the solution and adsorbed on the solid surface is not well examined. [10][11][12][13] Though the polymer-organic sol vent systems are extensively described in the literature, [14,15] the data about polymer solutions in inorganic polar solvents are relatively scare. [16] Moreover, knowledge about temperature dependences of high-molecular compounds adsorption on the solid surface is very poor.…”

The temperature effect on adsorption behavior of water soluble polymer and structure of its adsorption layer formed on the solid surface is presented. The main reasons for such problem explanation are wide application possibilities of stabilization-flocculation properties of polymers in many technological and ecological processes and very poor knowledge about temperature dependences of high-molecular compounds adsorption on the solid surface. To systematize the information about the effect of temperature on polymer chain conformation on the adsorbent surface the following aspects were considered: thermodynamic and physicochemical characteristics of polymer solutions, stabilization-flocculation properties of polymers in the dispersed systems, and presentation of respective experimental results. The theoretical and experimental evidence of the temperature effect on polymer macromolecule conformation on the solid surface presented in the article can contribute to better knowledge and understanding of the adsorption process at the metal oxide-polymer solution interface in the temperature function.

“…Bozdogan [7] applied the intrinsic viscosity-temperature data of polystyrene (PS) fractions in decalin, cyclohexane, dioctyl phthalate and toluene solutions in theta temperatures, and obtained solubility parameters. This author proposed an equation using the critical volume fraction and segment number of the polymer (PS) for calculating the partial molar entropy of a polymer in dilute solution.…”

“…In concordance with the modified treatment of Bozdogan [7], in this work we studied the thermodynamic properties of BSA in aqueous solutions within a temperature range of 35 to 40 ∘ C; the increase in relative viscosity ( ) was calculated for each case. In addition, this work proposes the hydrodynamic value of cohesion as an indicator of the degree of affinity of macromolecules with water and the thermodynamic implications of the conformational changes that water molecules present in association with BSA.…”

The behavior of bovine serum albumin (BSA) in water is scarcely studied, and the thermodynamic properties arising from the experimental measurements have not been reported. Intrinsic viscosity measurements are very useful in assessing the interaction between the solute and solvent. This work discussed in a simple determination of the enthalpy of BSA in aqueous solution when the concentration ranges from 0.2 to 36.71% wt. and the temperature from 35 to 40 ∘ C. The relationship between the concentration and intrinsic viscosity is determined according to the method of Huggins. The temperature increase reduces the ratio between inherent viscosity and concentration ( / ). This is reflected in the Van't Hoff curve. Furthermore, this work proposes hydrodynamic cohesion value as an indicator of the degree of affinity of protein with water and thermodynamic implications in conformational changes.
