DECOLOURIZATION AND REMOVAL OF PHENOL COMPOUNDS FROM OLIVE MILL WASTEWATER BY O-2/UV/NaBO2H2O2 center dot 3H(2)O

Abstract

The aim of this study was to evaluate the feasibility of decolourization and removal of colour, phenol and lignin in OMW by using O-2/UV/NaBO2H2O2 center dot 3H(2)O. The operating parameters were determined to find the suitable conditions for the best removal, such as; sodium perborate dosage, temperature, times, pH and effect of UV. From the experimental results, the photolytic degradation of color, lignin, and phenol was favorable at pH 9-11.0. Optimum values of sodium perborate and temperature were found to be 10gL(-1) and 298K, respectively. In addition, the pseudo-first order model was applied and r(2) values were noted from 0.90 to 0.99. It can be said that this study proves the effectiveness of photolytic removal for highly concentrated organic pollutants in OMW.
