“…This causes the generation of high energy electron-hole pairs (e À /h þ ), which may migrate to the surface of the catalyst and may either reunite producing thermal Due to some disadvantages of the heterogeneous photocatalysis (e.g., rather small quantum efficiency of the process; comparatively narrow light-response reach of TiO 2 ; the requirement of postseparation and recovery of the catalyst particles from the reaction mixture in aqueous slurry systems), TiO 2 appear to have some interesting properties, such as high chemical stability in a wide pH range, strong resistance to chemical breakdown and photocorrosion, and high efficiency. The catalyst is also inexpensive and can be reprocessed [134,156]. The characteristics of antibiotics to be treated like pKa and molecular structure will identify not only the performance of their photocatalytic breakdown but also the mechanisms of the oxidation products formation.…”

Antibiotics are nonbiodegradable, can survive at aquatic environments for long periods and they have a big potential bio-accumulation in the environment. They are extensively metabolized by humans, animals and plants. After metabolization, antibiotics or their metabolites are excreted into the aquatic environment. Removal of these compounds from the aquatic environment is feasible by different processes. But antibiotics are not treated in conventional wastewater treatment plants efficiently. During the last years studies with advanced oxidation processes (AOPs) for removal of these pharmaceuticals from waters has shown that they can be useful for removing them fully. Advanced oxidation processes (AOPs) can work as alternatives or complementary method in traditional wastewater treatment, and highly reactive free radicals, especially hydroxyl radicals (OH) generated via chemical (O 3 /H 2 O 2 ,O 3 /OH -), photochemical (UV/O 3 ,O 3 /H 2 O 2 ) reactions, serve as the main oxidant. This study presents an overview of the literature on antibiotics and their removal from water by advanced oxidation processes. It includes almost all types of antibiotics which are consumed by human and veterinary processes. It was found that most of the investigated advanced oxidation treatment processes for the oxidation of antibiotics in water are direct and indirect photolysis with the combinations of H 2 O 2 ,TiO 2 , ozone and Fenton's reagent.

“…In a previous study, the toxicity of atenolol's intermediates from photo/Fe/H 2 O 2 system process is higher than the parent compound (Veloutsou et al, 2014). Moreover, sulfamethoxazole removal from wastewater by solar photo/Fe/H 2 O 2 system increases the toxicity of the wastewater from 16% to 86%, as assessed by Vibrio fischeri bioassays (Trovo et al, 2009). Another important product in these pharmaceutical removal processes is Fe 2C or Mn 2C .…”

Pharmaceuticals are detected at trace levels in waters. Their adverse effects on aquatic ecosystems and human health demand novel pharmaceutical removal technologies for treating wastewater effluents. Iron (Fe) or manganese (Mn) may play important roles in these new technologies since these metals are abundantly available at low costs and are known to contribute to organic conversions via physico-chemical, chemical, and biologically related processes. Few reviews describe and discuss Fe-or Mn-based technologies for the purpose to remove pharmaceuticals from water. Therefore, we review the current literature sorted into the three removal mechanisms, that is., through physico-chemical, chemical, and biological processes. The principals, performance, and influential parameters of these three types of technologies are described. Current and potential applications of these technologies are critically evaluated in order to identify advantages and challenges. In addition, the Fe-or Mn-based technologies which are currently not used but promising to further develop to remove pharmaceuticals cost efficiently are proposed.

RESUMO -A presença de quantidades alarmantes de contaminantes emergentes no meio ambiente tem alertado a comunidade científica para a necessidade de desenvolver tecnologias alternativas capazes de remover estes contaminantes, uma vez que os processos convencionais são insuficientes. Neste contexto, os Processos Oxidativos Avançados (POA) têm-se revelado alternativas promissoras. De entre os POA mais aplicados estão os que se baseiam na reação de Fenton (Fe 2+ +H 2 O 2 ), porém estes processos apresentam algumas limitações operacionais, como, por exemplo, a reduzida faixa de pH em que se pode trabalhar. Dessa maneira, a utilização de um fonte sólida de ferro em vez de Fe(II) aparenta ser uma solução para tal limitação. Posto isto, neste trabalho foi estudada a reação tipo Fenton, baseada na reação entre uma fonte sólida de ferro -o ferro de valência zero (FVZ) -e um oxidante recentemente explorado -o persulfato (PS). O poluente modelo neste estudo foi o pesticida amicarbazona (AMZ). Avaliou-se o efeito da dosagem inicial de FVZ e PS, bem como do pH, permitindo concluir que o processo PS/FVZ é promissor para a remediação de águas contaminadas com AMZ.
