“…At 190 min, no residual PBSA or BSA was found in the reaction system; however, about 75% of their initial TOC still remained in the solution. Ay and Kargi [60] showed a similar observation when they studied the extent of TOC removal in amoxicillin antibiotic system by photo-Fenton-based oxidation technology. They reported that 53% TOC removal was achieved when amoxicillin (105 mg L −1 ) completely disappeared, at initially 100 mg L −1 H 2 O 2 , 40 mg L −1 Fe 2+ , and pH 3.5.…”

“…A study was performed by Ji et al [34] for the photodegradation of PBSA using UV-365 nm/TiO 2 ; they reported that the mineralization of PBSA to the end products (CO 2 and H 2 O) exhibited an extremely slow rate and a considerably long irradiation time (>12 h) was expected for a complete TOC removal. These results suggested that stable and photoresistant intermediates were probably produced and required a longer reaction time or higher UV fluence to achieve a complete mineralization [34,60,61].…”

“…The removal of antibiotics from waste water is a great concern regarding the prevention of bacterial resistance and side effects of exposure. Several methods have been reported to remove amoxicillin from aqueous media and include reversed osmosis, use of ion exchange resins (6), ozonation (5), oxidation by Fenton's reagent (7)(8)(9)(10), use of microand nanoscale iron particles (11), antibiotic removal by biological treatment (12), nanofiltration (13), membrane separation (14), and adsorption processes (15,16). Adsorption is considered a highly effective means to remove contaminants in water or wastewater even at very low concentrations (<1 mg/L) (15).…”

Multi-walled carbon nanotubes (MWCNT) were used to separate amoxicillin from aqueous media. The parameters affecting amoxicillin adsorption such as pH, temperature, time, interferences of similar molecules, and the amount of adsorbent used were studied. Amoxicillin adsorption using MWCNT was compared to that using Fullerene C60 and activated carbon (AC). The adsorption efficiency of 0.1 and 0.2 g of MWCNT using in a continuous mode were 86.5% and 87.9%, respectively. Evaluation of the adsorbent capacity showed that each gram of MWCNT can absorb 22.9 mg amoxicillin. The effect of pH was studied over the range 2-8 and revealed that adsorption of the amoxicillin at the initial pH of 4.6 was more effective than any other pH. The adsorption of amoxicillin on MWCNT was much greater than Fullerene C60 and AC. Adsorption data showed that they were best fitted to the Langmuir isotherm.

“…In general, these designs tend to have fewer design points than a CCD, which is less expensive to execute with the same number of factors [140,163]. A few studies have been published using this approach [29,120,155,164]. Ay and Kargi [164] applied this approach to maximize amoxicillin degradation and mineralization, studying the combined effect of drug concentration, oxidizing agent, and catalyst; finding that the effect of the oxidizing agent and the initial concentration of amoxicillin on the efficiency of the photo-Fenton process is more significant.…”

Currently there is a growing concern about the presence of emerging contaminants (EC) in water bodies and their potential ecotoxicological effects. Pharmaceuticals, a type of EC, are widely distributed in the environment and their main entry is through wastewater from treatment plants, since these systems are not designed to remove EC. In this sense, the photo-Fenton process, an advanced oxidation process, has proven to be highly efficient in degrading new potentially harmful contaminants. However, this process is affected by multiple factors, which makes it necessary to implement a methodological strategy to optimize the photo-Fenton process. Within these, the Taguchi method provides robust and low-cost solutions with the least number of experiments, providing knowledge of the contribution of each of the factors studied to the response variable. In addition to the above, the Taguchi method can be coupled to a Grey relational analysis (Grey–Taguchi method), which will allow the optimization of more than one response variable at the same time. This paper discusses the parameters that affect the photo-Fenton process and the application of designs of experiments to optimize the process.
