Regeneration of schungite sorbents containing petroleum products recovered from aqueous solutions
Thermooxidative regeneration removes petroleum products adsorbed by schungite sorbents from aqueous solutions. The retention of activity after regeneration ensures the recycling of the sorbents. The influence of the cyclic operation on the carbon content and the porous structure of the sorbents is considered.
