“…To the best of our knowledge this is the first time that TiO 2 coated on quartz tube was applied for BP-3 degradation. The method used in this study was superior to the other related studies in which TiO 2 nanoparticles was used as the catalyst [20, 26], because as apposed to those studies, in this study nanoparticles were coated on quartz tubes, so that no particles aggregation occurred. The best advantage of this method is that the catalyst can be used repeatedly and for a long time for BP-3 degradation in aqueous solution.…”

“…Traditional methods of wastewater treatment such as adsorption, filtration and flocculation can only transfer the organic pollutants from one phase to another which needs further treatment [17]. In the recent years, advanced oxidation process (AOP) with a promising ability to remove organic compounds, are being developed as a proper alternative to the traditional treatment methods [9, 18–20]. AOPs rely on in-situ production of highly reactive hydroxyl radicals (OH˙).…”

“…Heterogeneous photocatalysis using semiconductors, is one of the AOPs which has an effective ability to remove organic compounds [17]. Application of TiO 2 nanoparticles, especially in anatase polymorphic form, has been reported for degradation of different organic pollutants such as dyes [18], Diethyl phthalate [19], and BP-3 [20] . Mesoporous structure of this catalyst provides a large surface area for molecular transfer and enhances the degradation process [18].…”

“…Response surface methodology (RSM) has been applied in several studies to optimize the condition under which the most degradation efficiency of organic compounds would occur. RSM consists of a group of mathematical and statistical techniques for optimizing a response which is influenced by several independent variables [18, 20, 27, 28]. Central composite design (CCD) is the most appropriate model used for optimizing the condition under RSM design [28].…”

Background Benzophenone-3 (BP-3), one of the emerging pollutants, is commercially synthesized as UV filter used in cosmetics and other personal care products and its occurrence in the aquatic environment has widely been reported. The goal of this study was to enhance an AOP method for degradation of UV filter Benzophenone-3 in aqueous solutions . Method In this study, sol-gel method was applied to synthesis TiO 2 nanoparticles. Subsequently, the nanoparticles were successfully coated on quartz tubes. The synthesized catalyst was characterized using XRD, FE-SEM and EDX analysis. Then, the efficiency of photocatalytic process using TiO 2 coated quartz tubes for BP-3 degradation from synthetic and real aqueous solution was assessed. Result The optimum contact time and solution pH for the highest BP-3 degradation in the synthetic solution were found at 15 min and 10, respectively. The maximum degradation (98%) of BP-3 by photocatalytic process was observed at 1 mg/L initial BP-3 concentration using 225 cm 2 of catalyst surface area. Among the three applied kinetic models, the experimental data were found to follow the first-order equation more closely with the rate constant of 0.2, 0.048 and 0.035 1/min for 1, 3 and 5 mg/L of initial BP-3 concentration, respectively. In order to investigate the potential of this process for real effluent, the treatment of swimming pool water and wastewater treatment plant was examined and BP-3 degradation close to 88% and 32.1 was achieved, respectively. Conclusion Based on the obtained data, the photocatalytic process could successfully be applied for water treatment in swimming pools and other effluent containing BP-3 with low turbidity. The advantage of this study is that the synthesized catalyst can be used repeatedly needless to remove catalyst from the treated solution. In addition, AOP s can effectively eliminate organic compounds in aqueous phase, rather than transferring pollutants into another phase. The limitation of this study is that in solution with high turbidity photocatalytic degradation can be hampered and pre- treatment is needed to reduce turbidity.

“…BP3 has a destructive effect on the endocrine system of different organisms. The photocatalytic degradation of BP3 by particles of TiO 2 [83] showed that after 300 min of treatment, about 67% of dissolved organic carbon was eliminated while reducing toxicity and increasing biodegradability, confirming that photocatalysis with TiO 2 is a potential method for removing BP3 from water.…”

Environment-Friendly Removal Methods for Endocrine Disrupting Chemicals

In the past few decades, many emerging pollutants have been detected and monitored in different water sources because of their universal consumption and improper disposal. Among these, endocrine-disrupting chemicals (EDCs), a group of organic chemicals, have received global attention due to their estrogen effect, toxicity, persistence and bioaccumulation. For the removal of EDCs, conventional wastewater treatment methods include flocculation, precipitation, adsorption, etc. However, there are some limitations on these common methods. Herein, in order to enhance the public’s understanding of environmental EDCs, the definition of EDCs and the characteristics of several typical EDCs (physical and chemical properties, sources, usage, concentrations in the environment) are reviewed and summarized in this paper. In particular, the methods of EDC removal are reviewed, including the traditional methods of EDC removal, photocatalysis, biodegradation of EDCs and the latest research results of EDC removal. It is proposed that photocatalysis and biodegradation could be used as an environmentally friendly and efficient EDC removal technology. Photocatalytic technology could be one of the water treatment methods with the most potential, with great development prospects due to its high catalytic efficiency and low energy consumption. Biodegradation is expected to replace traditional water treatment methods and is also considered to be a highly promising method for efficient removal of EDCs. Besides, we summarize several photocatalysts with high catalytic activity and some fungi, bacteria and algae with strong biodegradability.
