The water effluents of olive presses contain a number of phenols thatare hardly biodegradable and therefore constitute an environmentalhazard, mainly in the Mediterranean countries. The present work presentsthe results obtained from the study of artificial solutions containingone kind of phenol, namely gallic acid that consists of the main type ofphenols present.According to the experimental procedure, the phenol is removed from thewater solution by absorption on different naturally occurring raw rockmaterials. The first material is caustic magnesia produced after thecalcination of a magnesite sample from Macedonia, Greece, the second isa sample of sedimentary psammitic marl from the area of Chania, Crete,Greece, and the third solid absorbent is a bentonite sample from theisland of Milos, Greece.According to the results obtained, magnesia seems to be by far the bestabsorbent, with an absorbing capacity of 3500 mg of phenol per gram,followed by the psammitic marl. The absorbing capacity of bentonite isalmost negligible.
