“…Accordingly, there is increasing interest to develop efficient treatment processes for controlling the occurrence of pharmaceutical pollutants in aquatic bodies. Advanced oxidation processes (AOPs) have been used widely to remove pharmaceutical compounds such as ozonation [8][9][10][11], ferrate (VI) [12,13], photocatalysis [14][15][16] and electrochemical oxidation [17,18]. Chemical oxidation with ozone is an efficient technology for the removal of organic pollutants, but the performance is often not strong enough due to its selectivity to remove some target pollutants in a realistic time and cost frame.…”

The advanced oxidation of paracetamol (PCT), frequently used analgesic, promoted by electro-oxidation (EOX), goethite catalyzed electro-Fenton (GEF) with goethite, ozonation and electro-peroxone (E-peroxone) was investigated. The degradation efficiency of the processes was evaluated considering the decay of PCT versus time. All the processes showed pseudo-first order character for PCT degradation. kobs values, at optimum conditions for an individual process, were defined as 0.0022, 0.0029, 0.0870 and 0.1662 min-1 for EOX, GEF, ozonation and E-peroxone processes, respectively. Where EOX and GEF processes showed poor degradation efficiencies, novel E-peroxone process provided complete removal of PCT. The degradation of the PCT would mostly occur by OH• and molecular O3 due to the higher rate constants achieved at E-peroxone and ozonation. Conversely, with lower kobs values gained at EOX, hydroxyl radicals would not contribute noticeably to the PCT degradation. In GEF process, due to relatively lower OH• production rate, lower kobs values were obtained for the degradation of PCT. The formation of reaction intermediates, aromatics and carboxylic acids, was also determined in this study.

“…Generally, the powder is dispersed in non-volatile liquid paraffin (Nujol) that has low absorption in the infrared region. FT-IR provides a primary peak for ferrate salt around 808 cm -1 and a shoulder peak can also be observed approximately at 780 cm -1 , which point out to the asymmetric stretching vibrations of the ironoxygen bond in the ferrate(VI) compound [74]. The more the intensity of the characteristic vibrational peak of ferrate(VI) is strong, more the purity of the prepared ferrate(VI) is also higher.…”

“…When used as a disinfectant, studies have shown that ferrate(VI) salt is more effective than chlorine in reducing different types of bacteria and viruses [37,78]. Furthermore, ferrate(VI) has been used to control odour, to remove pharmaceutical pollutants such as amoxicillin, ciprofloxacin, 2,4-dichlorophenoxyacetic acid, and flurbiprofen from wastewater [74], to stabilise and dewater primary sludge [83], and to remove freshwater humic substances from water [84].…”

“…Moreover, the combined application of low concentration of ferrate(VI) (below 0.5 ppm) and Fe(III) as the main coagulant agent was found to be an effective process for the arsenic removal. Pharmaceuticals in water and wastewater treatment processes, including photo-catalytic degradation, ozonation and other AOPs have been explored by several researchers [74]. Lately, ferrate(VI) has been studied widely, as it could be an effective alternative to conventional AOPs for the degradation of pharmaceutical pollutants.…”

Investigation into the production, characterization and application of ferrate(VI) in water and wastewater treatment to enable metal removal through oxidation and coagulation processes and recommended in perspective for AMD treatment as a sustainable process. Revieworganic chemicals, endocrine disrupting chemicals, heavy metals, metal-complexed species, and others in water decontamination processes. Studies also showed that ferrate(VI) salt can be classified as a green chemical which can replace different disinfectants and oxidants producing toxic disinfectant by-products generated by the use of chemicals such as chlorine and chlorine dioxide. Mining industry is another sector, which still has a problem of high energy consumption during acid mine drainage (AMD) treatment. This is due to extensive stirring and aeration which required to facilitate the oxidation of Fe(II) ions. However, the authors recommend the use of ferrate(VI) salt for AMD treatment as it can work as a powerful oxidant converting Fe(II) to Fe(III) and act as a coagulant in a single treating unit, hence, thus reducing energy consumption and environmental pollution problems.

“…So far, numerous methods have been studied for the removal of antibiotic CIP from aquatic environments. Among the most common methods are adsorption, ozonation, and photocatalytic processes (7,8). Considering the costliness and production of intermediate products by the abovementioned methods, biological processes have attracted a great deal of attention thanks to being environment friendly and not needing advanced facilities (9).…”

The presence of pharmaceutical wastewater containing antibiotic compound is one of the new problems relating to the environmental pollution. Antibiotic ciprofloxacin (CIP), widely used in medical treatments, can induce antibiotic resistance in low concentrations in the ecosystem and aqueous solutions. In this study, CIP was removed using moving bed biofilm reactor (MBBR) from real hospital-derived wastewater. This study was carried out at Beasat hospital in Hamadan, Iran. CIP (100 mL) was applied in 2 sets of plexiglass tubular columns as MBBR. Microorganisms were grown on the suspended carriers. To achieve this purpose, polyethylene kaldnes (K1) was chosen as reactor bed in 500 m 2 /m 3 specific area. The effect of operating parameters such as mixed liquor suspended solid (MLSS) (100, 1000, 3000 mg/L), hydraulic retention time (HRT) (8, 12, 24 hours), and support media with carrier K1 (30%, 50%, 70%) were evaluated. According to the results, the yield of CIP removal at 30%, 50%, and 70% of K1, reaction of 24 hours at MLSS 3000 mg/L was obtained 50.5%, 68.9%, and 97.6% respectively. In the same conditions, chemical oxygen demand (COD) removal was achieved 26.78%, 30.49%, and 80.07%, respectively. Results indicated that the MBBR process can be used as an effective approach for removing CIP and COD from hospital effluent. Moreover, these data suggested that the K1 carrier could be useful in terms of mineralization and efficiency. Furthermore, development of biofilm in MBBR was mostly affected by K1.
