“…Based on the surface or subsurface flow direction, systems are classified as horizontal or vertical [129]. The efficiency of horizontal subsurface flowconstructed wetlands (HSSFCWs) in nitrobenzene degradation was examined by Kirui et al [130]. The study was conducted using two lab-scale wetlands planted with Juncus effusus.…”

“…Based on the findings, both wetlands performed at 99% NB removal overall. It has been suggested that detailed microbial reactions involving NB as an electron donor and sulfate as an electron acceptor produce high concentrations of generated sulfide [130]. Regardless of external carbon sources, a study on three CW groups (glucose, starch, and blank CW group) showed effective removal of NB and COD in wastewater with a low NB concentration (<50 mg/L).…”

Nitroaromatic compounds (NACs), which are widely used in pesticides, explosives, dyes, and pharmaceuticals, include nitrobenzene, nitrotoluenes, nitrophenols, and nitrobenzoates. They are also significant industrial pollutants in the environment. These substances, as well as their derivatives, frequently have toxic or mutagenic properties. Wastewater containing nitroaromatic compounds can be effectively managed by using biological treatment methods that are accessible, cost-effective, and environmentally friendly. This review highlights the latest developments in biological treatment systems for removing NACs from wastewater. The large-scale implementation of biological treatment systems will be facilitated by future studies that focus on identifying the best operational methods and that determine how co-pollutants impact the removal of NACs from wastewater.

“…Nitrobenzene (Ph-NO 2 ) and its derivatives are widely used in industry as pesticide and dyes; however, their irresponsible discharge has caused severe environmental pollutions because these chemicals are difficult to be degraded in nature [1,2]. These toxic chemicals distributed in the surface and groundwater could be intaken by humans through the food chain, rising the cancer risk of humans [3,4]. Therefore, the degradation of nitrobenzene is imminent in environmental safety fields [5].…”

Nitrobenzene compounds are highly toxic pollutants with good stability, and they have a major negative impact on both human health and the ecological environment. Herein, it was found for the first time that fluorescent DNA-silver nanoclusters (DNA-AgNCs) can catalyze the reduction of toxic and harmful nitro compounds into less toxic amino compounds with excellent tolerance to high temperature and organic solvents. In this study, the reduction of p-nitrophenol (4-NP) as a model was systematically investigated, followed by expending the substrate to disclose the versatility of this reaction. This report not only expanded the conditions for utilizing catalytic reduction conditions of DNA-AgNCs as an efficient catalyst in the control of hazardous chemicals but also widened the substrate range of DNA-AgNCs reduction, providing a new angle for the application of noble metal nanoclusters.

“…It also can cause methemoglobinemia, fatigue, dizziness, headache, and nausea [ 3 ]. In the industrial wastewater streams, the concentration of NB has been detected as high as 35–140 mg/L [ 4 , 5 ]. The national institute for occupational safety and health recommends an occupational exposure limit of 23 mg/m 3 of NB for a 10 h workday.…”

A novel cellulose–styrene copolymer adsorbent (cellulose-St) was prepared using free radical polymerization. Successful polymerization was confirmed through Fourier Transform Infrared Spectroscopy (FTIR), Carbon 13 Solid Nuclear Magnetic Resonance (13C NMR) Spectroscopy, Scanning Electron Microscopy (SEM), etc. Cellulose-St possessed good hydrophobicity, and the best water contact angle of cellulose-St samples could reach 146°. It had the ability of adsorption for nitrobenzene (NB), and the adsorption process could be well described by the pseudo-second-order (R2 > 0.99) and three-stage intraparticle diffusion (R2 > 0.99) kinetic models. Furthermore, the dynamic adsorption experiments revealed that cellulose-St had the potential for continuous separation of NB in water, and the breakthrough point for the initial NB concentration of 10 mg/L reached 1.275 L/g. Moreover, cellulose-St exhibited excellent environmental adaptability that it could maintain its hydrophobicity and adsorption ability for NB in strong acids, strong alkalis, or organic solvents. The used cellulose-St could be reused after washing with ethanol and keep almost constant adsorption capacity after ten cycles.
