The water effluents of olive presses contain a number of phenols that
are hardly biodegradable and therefore constitute an environmental
hazard, mainly in the Mediterranean countries. The present work presents
the results obtained from the study of artificial solutions containing
one kind of phenol, namely gallic acid that consists of the main type of
phenols present.
According to the experimental procedure, the phenol is removed from the
water solution by absorption on different naturally occurring raw rock
materials. The first material is caustic magnesia produced after the
calcination of a magnesite sample from Macedonia, Greece, the second is
a sample of sedimentary psammitic marl from the area of Chania, Crete,
Greece, and the third solid absorbent is a bentonite sample from the
island of Milos, Greece.
According to the results obtained, magnesia seems to be by far the best
absorbent, with an absorbing capacity of 3500 mg of phenol per gram,
followed by the psammitic marl. The absorbing capacity of bentonite is
almost negligible.
