Abstract
Oreto river is one of the sources from which the city of Palermo deriv es its water supply. The present paper reports a systematic analytical investigation carried out on four sites and in different seasons. The main physico-chemical parameters that were determined are: temperatur e, pH, specific conductance, dissolved oxygen (DO), chemical oxygen de mand (COD), biochemical oxygen demand (BOD5), concentration of nitroge n containing species (NH4+, NO2-, NO3-), total phosphorus and anionic surfactants. The sodium adsorption ratio (SAR) has been determined in order to establish the suitability of the water for irrigation. Moreov er, in order to prove the effectiveness of the photocatalytic method t o degrade organic pollutants dissolved in an actual water effluent, so me experiments were carried out by irradiating in a batch photoreactor water samples withdrawn from the river. Polycrystalline TiO2 (mainly in the anatase phase) was used as photocatalyst.
