Abstract

In this work we have studied the adsorption of oligobutadiene rubber (synthetic rubber) on native
carbon black in comparison to heat-treated samples. Statical (batch) method has been used to determine isotherms
of adsorption. Experimental error was less then 3%. We found that thermal treatment of native carbon
black increases adsorption of synthetic rubber from diluted n-heptane solution. Obtained isotherms of adsorption
allow us to calculate distribution coefficients and differential Helmholtz energy for studied systems. In
comparison to native carbon black, heat-treated samples showed the higher adsorption performance due to
specific interactions at the solid-liquid interface.
