“…Perchlorate is a drinking water contamination of interest due to its high mobility and inhibitory effect on thyroid functions (Cetin et al, 2015 ; Ucar et al, 2017 ). Among the treatment alternatives, biological reduction is a cost effective method (Ucar et al, 2015a , b , 2016 ).…”

“…Inorganic electron donors also have their own disadvantages, for example, when sulfur is used, sulfate and acidity can occur in the effluent. However, in recent studies, the use of the advantages of both systems in the removal of nitrate and perchlorate from drinking and underground waters and the elimination of disadvantages are becoming increasingly widespread (Ucar et al, 2015b , 2017 ).…”

Microbial fuel cells (MFC) have recently received increasing attention due to their promising potential in sustainable wastewater treatment and contaminant removal. In general, contaminants can be removed either as an electron donor via microbial catalyzed oxidization at the anode or removed at the cathode as electron acceptors through reduction. Some contaminants can also function as electron mediators at the anode or cathode. While previous studies have done a thorough assessment of electron donors, cathodic electron acceptors and mediators have not been as well described. Oxygen is widely used as an electron acceptor due to its high oxidation potential and ready availability. Recent studies, however, have begun to assess the use of different electron acceptors because of the (1) diversity of redox potential, (2) needs of alternative and more efficient cathode reaction, and (3) expanding of MFC based technologies in different areas. The aim of this review was to evaluate the performance and applicability of various electron acceptors and mediators used in MFCs. This review also evaluated the corresponding performance, advantages and disadvantages, and future potential applications of select electron acceptors (e.g., nitrate, iron, copper, perchlorate) and mediators.

“…Perchlorate salts are often used for chemical operations in the military munitions and the chemical and nuclear industries. Previous studies have found that the perchlorate anions are naturally present in soil and groundwater together with nitrate ones, and wastewater discharged from improper treatment processes contains a high concentration of the anions. − In addition, it has been considered that the solubility, mobility, and stability of the perchlorates in soil and groundwater are higher than those of the nitrate one and that the perchlorates as contaminant plumes present widespread impacts on human health and the environment. Therefore, metal perchlorates such as sodium (Na + ), potassium (K + ), cesium (Cs + ), magnesium (Mg 2+ ), calcium (Ca 2+ ), strontium (Sr 2+ ), lanthanum (La 3+ ), and uranyl (UO 2 2+ ) were adopted for elucidating the potentiality as a sensing material for UO 2 2+ in wastewater discharged from nuclear-related facilities.…”

To avoid environmental and biological impacts linked to uranium-contaminating solutions, the development of sensitive and selective uranium detection techniques for solutions has become a critical issue. Although various kinds of detection methodologies have been developed, they are still not totally satisfactory in terms of simplicity, efficiency, and versatility. In this work, a novel chemosensor bearing a diaza-18-crown-6 ether and two naphthalimides (PN-DCE) was synthesized for simple, selective, rapid, and cost-effective detection of uranyl ions (UO 2 2+ ) and characterized by 1 H-, 13 C-NMR, FT-IR, ESI-TOF-MS, and elemental analysis. Effects of various metal ions

“…The high concentrations of nitrate in drinking water (>10 mg N/l) would have a high risk to produce nitrosamines and cause methemoglobinemia, which was harmful to people's health [ 3 , 4 ]. Therefore, a lot of methods to reduce nitrate from water sources have been reported [ 5 , 6 ].…”

This study investigated the performance of an autohydrogenotrophic membrane biofilm reactor (MBfR) to remove nitrate from water with high sulfate concentrations. The results of simulated running showed that TN removal could be over than 98.8% with the maximum denitrification rate of 134.6 g N/m3 d under the conditions of the influent sulfate concentrations of 300 mg SO42−/l. The distribution ratio of H2 electron donor for nitrate and sulfate was 70.0 : 26.9 at the high influent loading ratio of sulfate/nitrate of 853.3 g SO42−/m3 d : 140.5 g N/m3 d, which indicated that denitrification bacteria (DB) were normally dominated to complete H2 electron with sulfate bacteria (SRB). The results of molecular microbiology analysis showed that the dominated DB were Rhodocyclus and Hydrogenophaga, and the dominated SRB was Desulfohalobium, under the high influent sulfate concentrations.
