Özet
The adsorption equilibrium of dark-coloured Compounds from apple juice has been investigated as a function of several variables including activation conditions of bentonite (heat and acid treatments), clay concentrations (2 x 10(-3)-8 x 10(-3) kg clay/dm(3) apple juice) and temperature (range of 296-336 K). The adsorption efficiency with acid-activated bentonite was greater than that with heat-activated and native bentonite, depending on surface properties; specific surface areas were 95.31, 71.95 and 71.76 m(2)/g, respectively.
