| الوصف: | Du Nooy ring and oscillating droplet methods are used to study the adsorption and dilatation rheological characteristics (viscoelastic modulus and phase angle) of aqueous solutions of humic acid salts at liquid-gas interfaces. It is established that the equilibrium surface tension and limiting surface elasticity of humic acid salt solutions are in good agreement with the model of a real two-dimensional solution that was previously proposed for biopolymers. Based on the results of analyzing dynamic surface tension and adsorption kinetics, it is shown that humic acid salts are characterized by a nondiffusion (barrier) adsorption mechanism. |
