Two methods of modification of benthonite used in vine clarification have been applied: introduc- tion of Na2S in report 1:10 into benthonite paste followed by pyrolysis at 450oC; electrotreatment of slime suspension in electrochemical cell (in anodic camera and in diaphragmless electrolizer). By means of ther- mogravimetric analysis some thermal effects attributed to different processes have been observed: removing of water (dehydratation), phase transformations, oxidation of organic compounds, crystallization and de- struction of benthonite structure. Adsorption-structural characteristics of initial and modified samples of ben- thonite slimes have been examined and the mechanism of their change under thermo- and electrotreatment has been discussed.
