“…170,200,201 One of the issues of peroxicoagulation is to control the increase in solution pH with electrolysis time which is due to the hydrogen evolution reaction as occurs in the electrocoagulation process. [202][203][204] Thus, peroxicoagulation is a combination of the electro-Fenton process and electrocoagulation process, in which electro-Fenton predominates under acidic conditions, while electrocoagulation predominates under neutral and alkaline conditions. 205,206 However, external aeration during the peroxicoagulation process is an advantage for the oxidation of arsenite even under alkaline and neutral conditions, as aerated iron electrocoagulation is found effective for the oxidative sorption of arsenite from water.…”

“…In recent years, the environmental hazards caused by textile and dyeing industry wastewater have been increasing, which is mainly reflected in the fact that the wastewater produced not only destroys the natural environment but also flows into residential areas. Especially, dyestuff wastewater is difficult to decompose naturally and exists for a long term in the ecological cycle, which causes skin or respiratory diseases and damages human health. − In order to remedy the worsening water environment, many treatments, including physical adsorption, , microbiological degradation, − electrocatalytic degradation, − and photocatalyst degradation, were used to treat dyestuff wastewater. Among them, the photocatalysis technology is gaining significant attention as a clean and energy-saving method. , The key limitation to the large-scale application of the photocatalysis technology is the lack of inexpensive, safe, and high-efficiency photocatalysts.…”

In this work, 0.75 wt ‰ 2,3-pyridinedicarboxylic anhydride (PDA) as a novel dopant was utilized to obtain modified graphitic carbon nitride with ultratrace doping (3MCN-PDA 3 ) by facile thermal polymerization. Characterization of the microstructure, surface state, and porosity properties of the samples indicated that 3MCN-PDA 3 has a thinner sheet-like, larger-scale, and tighter lamellar stacking structure than that of pristine graphitic carbon nitride (3MCN). Based on photo/electrochemical analysis, the PDA dopant formed an extended coplanar conjugated system by anhydride-amine thermal condensation with heptazine rings, and the channels of amide covalent bonds and superconjugation of the solitary pair of electrons of the nitrogen atoms of PDA synergistically promoted the charge transport performance of 3MCN-PDA 3 . Under visible light, the photodegradation efficiency of Rhodamine B (RhB) over 3MCN-PDA 3 reached 92.4% in 60 min and realized almost entire removal in 200 min (99.2%), 1.43 times that of 3MCN. Furthermore, the experimental results and generalized density theory calculations confirmed that PDA acts as an intermediate molecular island and constructs an efficient carrier transfer pathway between different heptazine units. The results indicate that PDA is a promising candidate to enhance the charge transfer performance through ultratrace doping in the large-scale preparation and application of the graphitic carbon nitride photocatalyst.

“…MFC is a bioelectric device that harnesses the natural metabolism of bacteria to generate electrical energy. Traditional fuel cells, such as hydrogen fuel cells, require energy to generate hydrogen, whilst MFCs do not require any external energy source, produce no additional greenhouse gases and are self-contained and biodegradable [17]. Thus, MFC is a potential contender for upcoming sustainable green energy sources due to these key advantages over conventional fuel cells [18].…”

Bioelectrochemical systems are a new secondary effluent treatment method where bacteria degrade industrial sludge and generate electricity for the external circuit. In this study, paper industry wastewater effluents were treated in microbial fuel cells (MFCs) by utilising six different sets of electrodes to produce bioelectricity. Bacterial biofilms were studied by field emission scanning electron microscopy (FESEM). Investigation disclosed that zinc mesh and carbon plate (MFC-2) had the highest power generation as observed with 1193 mV of output voltage, 2.69 mA output current and 533 mW/m2 power density along with 92% BOD removal without electrolyte solution. The lowest 325 mV of output voltage, 0.15 mA of output current and 7.0 mW/m2 of power density with 37% removal of BOD were measured for MFC-3, which was constructed with Al mesh and carbon plate. A total of 1.0 M CuSO4.5H2O cathodic electrolyte solution was added in MFC-5 with zinc and copper plates as electrodes, which enhanced the power generation and BOD removal. The highest output voltage, current and power density were obtained for MFC-5 with the magnitude of 1185 mV, 4.79 mA and 939 mW/m2, respectively.
