REMOVAL OF PHTHALATES FROM CONTAMINATED WATER USING DIRECT PHOTOLYSIS AND UV/H2O2 PROCESSES
This study was conducted to evaluate the removal efficiency of phthalate from contaminated water using the direct photolysis and the ultraviolet / hydrogen peroxide (UV/H2O2) process. Dimethyl phthalate (DMP) with an initial concentration of 20 ppm was used as a model compound. A lowpressure mercury...

| description | This study was conducted to evaluate the removal efficiency of phthalate from contaminated water using the direct photolysis and the ultraviolet / hydrogen peroxide (UV/H2O2) process. Dimethyl phthalate (DMP) with an initial concentration of 20 ppm was used as a model compound. A lowpressure mercury UV lamp of 100 mWatt intensity was used to provide the radiation. The effects of initial concentration of H2O2, UV exposure time, pH and temperature were assessed. The results showed that about 60 % of DMP were removed directly by activation caused by UV light after an exposure time of one hour. However, the removal efficiency increased when the DMP-spiked water was first dosed with H2O2 prior to irradiating with UV light (i.e. UV/H2O2). More than 98% of DMP was removed after 45 minutes when the UV-irradiated solution was dosed with 136 ppm of H2O2. The results also showed that lowering the pH and increasing the temperature enhanced the removal of DMP by UV/H2O2 process. |
