%X The present work evaluated
the use of photo-Fenton process for the treatment of kraft pulp mill effluent. The
photo-Fenton best operating conditions, such as pH, concentration, and H<sub>2</sub>O<sub>2</sub>:<i> </i>Fe<sup>2<i>+</i></sup> ratio were evaluated. The efficiency of the treatment was measured
by <i>COD</i> (chemical oxygen demand) removal.
The results showed that the optimum pH for the photo-Fenton process was equal to
3. The increase in H<sub>2</sub>O<sub>2</sub> application resulted in an efficiency
increase of the photo-Fenton process, although this was not a directly proportional
relation. For most cases, the H<sub>2</sub>O<sub>2</sub>: Fe<sup>2+</sup> proportion
of 100:1 yielded the best results for <i>COD</i> removal. Solar radiation was more efficient than artificial UV to the <i>COD</i> removal. During the treatment the organic
matter of the effluent was more oxidized than mineralized, showing a higher removal
of <i>COD</i> than <i>BOD</i> (biochemical oxygen demand) and <i>TOC </i>(total organic carbon), respectively. So, photo-Fenton process increased
the <i>BOD</i>/ <i>COD</i> ration but decreased the <i>BOD</i>/<i>TOC</i> ratio.
