Manufacturing of olive oil is of fundamental economic importance for many Mediterranean countries (Tunisia, Italy, Greece, Spain. ..). However this process involves an intensive consumption of water and produces large amounts of Olive Mill Wastewater (OMW), that is released without any treatment into the aquatic environment causing deleterious environmental effects [1]. OMWs are a serious environmental and social problem in Mediterranean countries [2], due to the high pollutant load, seasonal discharge, type and quality of the pollutants and difficulties to find technically and economically favourable solution.

Double-chain surfactants with two sulfonate groups were proposed for micellar elec-trokinetic chromatography (MEC) analysis of phenolic pollutants in water °. CE with ESI-MS detection was applied to the analysis of phenolic compounds in olive mill wastewaters. Quantitative analysis was performed in the negative SIM mode, using p-chlorophenol as internal standard. LOD ranged from 1 pg for 4-hydroxybenzaldehyde and protocatechuic acid (27) to 386 pg for vanillic acid (38) °". A modified montmorillonite served for SPE preconcentration of phenols, followed by EtOH desorption and CE end analysis .

Olive oil is nowadays produced by either two or three-phase extraction systems. The three phase method in which a solid fraction (wet pomace or alperujo), a liquid residue ( alpechin ), and the olive oil are obtained. Two phase method in which a solid fraction, wet pomace and a liquid one, the olive oil, are obtained. The main advantage of the two-phase system is the reduction of the olive mill wastewater amoimts compared to that originated from the three phase technology, in which 0.6-1.31 water/kg olives are used at the centrifugation step, by eliminating the production of alpechin thus avoiding its consequences environmental...
