Based on the advantages of the method described in this study, it can be concluded that additional studies are worthy of investigation by future work to explore the treatability of different types of pharmaceuticals and intermediates during the treatment.…”

“…In the present experiments, wastewater was kept for 1 day in a measuring cylinder for settling and thereafter, COD measurements were conducted with the sample taken from the supernatant of the wastewater. Su et al [26] indicated that leaving the samples overnight prevented the remaining H 2 O 2 from affecting COD measurements. The seperating point of effluent and sludge could not be determined even waiting for 1 day.…”

“…Recent studies show that in addition to advanced oxidation processes (AOPs) [16][17][18][19][20][21][22][23][24][25][26], adsorption [10], pure bacterial cultures [27], active sludge [28], subsurface flow constructed wetlands [29] and anaerobic treatment [20] can be used for PCT removal from wastewater. In the traditional environmental engineering technologies, wastewater treatments are usually realized by the parameters: chemical oxygen demand (COD), 5-day biological oxygen demand (BOD 5 ), and total organic carbon (TOC).…”

“…been reported yet for the pretreatment of a high strength pharmaceutical wastewater. It is apparent from the literature that although much attention has been given to the treatment of synthetic wastewater [21][22][23][24][25][26], there are almost no systematic papers available in the literature specifically devoted to a study of real PCT wastewater. It is seen that synthetic PCT wastewaters have been used in most of the recent studies.…”

Eliminación de fluoxetina presente en aguas contaminadas usando procesos fotoquímicos de oxidación avanzada y luz solar

“…Debido a la gran producción y prescripción de FLX en el mundo entero, su excreción en forma de orina o heces y la ineficiencia de las plantas convecionales de tratamiento de aguas, la presencia del fármaco en suelos, aguas residuales, aguas superficiales e incluso en agua potable ha sido reportada (Su et al, 2013) (Salazar et al, 2016). Es así como la FLX se ha detectado en aguas superficiales de Estados Unidos y Canadá en concentraciones de 0.012 y 0.013 -0.046 μg L -1 , respectivamente; en los efluentes de plantas de tratamiento de aguas a concentraciones de 0.038 -0.099 μg L -1 en Canadá y de 0.0017 μg L -1 en Corea del Sur; de 0.0006 -0.0187 μg L -1 en aguas residuales en Noruega; mientras que de 0.021 μg L -1 en aguas residuales de Estados Unidos.…”
