How do temperature and chemical structure affect surface properties of aqueous solutions of carboxylic acids?

- The surface properties of binary systems of aqueous-organic acid calculated.
- The activity coefficients of components have been calculated by UNIFAC methods.
- The interaction energy values were calculated by using LWW model.
- The U12-U11 value shows same behavior for studied systems with rising temperature.
- The relative Gibbs adsorption increases with increasing the length of carboxylic acid chain.
