“…Antibiotic contamination in wastewater and the environment can be reduced effectively via photocatalytic degradation when appropriate nanocatalysts are used. [4][5][6][7][8] In this direction, nanosized II-VI semiconductors have attracted much attention from researchers due to their unique physical characteristics and adequate optical bandgap, which endow them with effective photocatalytic activities. Among all other available semiconductors, zinc sulphide (ZnS) is the most interesting II-VI semiconductor owing to its stable cubic zinc blende crystal structure.…”

“…A comparison of this study with several ciprofloxacin degradation methods is shown in Table 2. It can be seen that the effect of this method tends to have a better degradation efficiency than photocatalytic [12,56] and Fenton oxidation [57], ozonation microbubble [11] and lower than the ozonation system [58]. However, if we look in more detail at ozonation by Wajahat et al [58], the initial concentration is too small, namely, 7.9 mg/L, while in this study it was able to effectively achieve ciprofloxacin degradation at high ciprofloxacin concentrations, namely 30 mg/L.…”

“…In addition, degradation with ferrates can be carried out at room temperature, making it easier to observe. Fenton oxidation Fe 2+ /H2O2 pH = 3.5, initial concentration = 15 mg/L 74.40 [57] Ozonation Ozone pH = 9, initial concentration = 7.91 mg/L 98.7 [58] Ozonation microbubbles Ozone pH = 7, concentration = 10.94 mg/L 83.5 [11] Determination of the mechanism of the degradation reaction Chromatogram results from LC-MS analysis of ciprofloxacin degradation products with ferrate (VI) have several peaks with different retention times as shown in Figure 10 and Table 3. N and O atoms in ciprofloxacin are able to donate their lone pair to Fe (VI) to form complex compounds.…”

Degradation of Ciprofloxacin (CIP) Antibiotic Waste using The Advanced Oxidation Process (AOP) Method with Ferrate (VI) from Extreme Base Electrosynthesis

2023

Ciprofloxacin (CIP) antibiotic liquid waste is the most common waste found in hospital discharge waters. The accumulation of CIP can increase mutation, microbial resistance, and toxicity in the environment due to its low biodegradability and longevity in waters. Thus, methods for eliminating CIP are important. The Advanced Oxidation Process (AOP) method with ferrate (VI) has good redox potential in water disinfection, and degradation of organic and inorganic pollutants. Therefore, this study aims to degrade CIP waste with ferrate (VI). The ferrate (VI) used was synthesized from the electrolysis of transformer scrap metal plates under extremely alkaline conditions. The success of the synthesis was proven by the presence of FeO(OH) groups characterized using FTIR, XRF, and XRD. Then, the effect of time, pH, and CIP degradation was studied. The results showed that the maximum performance was obtained at pH 7 and 120 min with the addition of 1.1 mg ferrate at initial CIP concentration of 30 mg/L. The concentration of CIP decreased with increasing treatment time which was confirmed by UV-Vis Spectrophotometer. This condition is able to degrade 86.7 % of CIP. In addition, the LC-MS results show that degradation occurs due to a reaction between HFeO4-/H2FeO4 and the active site of piperazine ring antibiotics. This shows that Ferrate has a promising potential to reduce ciprofloxacin antibiotic pollution from hospital wastewater for a better environment.

“…Currently, many techniques have been applied to treat fluoroquinolone-containing wastewater, including chemical precipitation, photolysis, ion exchange, coagulation and flocculation, complexation, ozonation, advanced oxidation processes, membrane filtration, biological remediation, and activated carbon adsorption [ 8 , 9 , 10 , 11 ]. With the development of the technologies, some of these technologies have low costs and relatively high removal efficiency [ 12 ]. However, these methods suffered from the disadvantages of potential toxic degradation products and long treatment time [ 13 , 14 ].…”

The low-cost calcium-based bentonite modified with anionic and cationic surfactants was granulated by cross-linking to sodium alginate (SA) to promote the adsorption efficiencies of norfloxacin (NOR). The characterization studies illustrated that the intercalation of cetyltrimethylammonium bromide (CTAB) and sodium dodecyl benzene sulfonate (SDBS) was successful. The modification improved the pore structure and the granular SA/organically modified bentonite composite (GOMBt) exhibited a lamellar structure with some roughness. The adsorption kinetics and isotherms indicated that adsorption of NOR on GOMBt was an endothermic process. The effects of various factors on the adsorption of NOR suggested that the maximum adsorption capacity was obtained under acidic conditions and cations improved the adsorption process. A fixed-bed column was employed to investigate the dynamic adsorption characteristics of NOR by GOMBt. The breakthrough time and bed height had a positive correlation; however, the relation of flow rate, pH, and breakthrough time had a negative correlation. The results showed that the dynamic adsorption data of NOR on GOMBt fitted Thomas and Yoon–Nelson models. The internal and external diffusion in GOMBt dynamic adsorption was not a rate-limiting step.
