“…Whilst current global estimates of benzenoid (molecules containing a benzene ring) emission to the atmosphere by vegetation are of a comparable order to those of anthropogenic activity (∼ 5 times lower; Misztal et al, 2015), and background concentrations of benzene are enhanced by increased biomass burning (Archibald et al, 2015), emission of benzene to the urban atmosphere is dominated by vehicle exhausts (Gentner et al, 2012) and solvent evaporation (Hoyt and Raun, 2015). As well as a toxin (Snyder et al, 1975) and carcinogen (Bird et al, 2010;Ruchirawat et al, 2005Ruchirawat et al, , 2007, benzene is photochemically active and contributes to the formation of ozone (O 3 ) and secondary organic aerosol (SOA), both of which act to modify the climate and contribute to poor air quality (Henze et al, 2008;Ng et al, 2007). SOA formation from benzene has previously been quantified with a focus on the contribution from smaller mass, ring-breaking reaction products such as epoxides (Glowacki et al, 2009) and dicarbonyl aldehydes (e.g.…”

Abstract. Aromatic hydrocarbons are a class of volatile organic compounds associated with anthropogenic activity and make up a significant fraction of urban volatile organic compound (VOC) emissions that contribute to the formation of secondary organic aerosol (SOA). Benzene is one of the most abundant species emitted from vehicles, biomass burning and industry. An iodide time-of-flight chemical ionisation mass spectrometer (ToF-CIMS) and nitrate ToF-CIMS were deployed at the Jülich Plant Atmosphere Chamber as part of a series of experiments examining benzene oxidation by OH under high- and low-NOx conditions, where a range of organic oxidation products were detected. The nitrate scheme detects many oxidation products with high masses, ranging from intermediate volatile organic compounds (IVOCs) to extremely low volatile organic compounds (ELVOCs), including C12 dimers. In comparison, very few species with C≥6 and O≥8 were detected with the iodide scheme, which detected many more IVOCs and semi-volatile organic compounds (SVOCs) but very few ELVOCs and low volatile organic compounds (LVOCs). A total of 132 and 195 CHO and CHON oxidation products are detected by the iodide ToF-CIMS in the low- and high-NOx experiments respectively. Ring-breaking products make up the dominant fraction of detected signal and 21 and 26 of the products listed in the Master Chemical Mechanism (MCM) were detected. The time series of highly oxidised (O≥6) and ring-retaining oxidation products (C6 and double-bond equivalent = 4) equilibrate quickly, characterised by a square form profile, compared to MCM and ring-breaking products which increase throughout oxidation, exhibiting sawtooth profiles. Under low-NOx conditions, all CHO formulae attributed to radical termination reactions of first-generation benzene products, and first-generation auto-oxidation products are observed. Several N-containing species that are either first-generation benzene products or first-generation auto-oxidation products are also observed under high-NOx conditions. Hierarchical cluster analysis finds four clusters, of which two describe photo-oxidation. Cluster 2 shows a negative dependency on the NO2/NOx ratio, indicating it is sensitive to NO concentration and thus likely to contain NO addition products and alkoxy-derived termination products. This cluster has the highest average carbon oxidation state (OSC‾) and the lowest average carbon number. Where nitrogen is present in a cluster member of cluster 2, the oxygen number is even, as expected for alkoxy-derived products. In contrast, cluster 1 shows no dependency on the NO2/NOx ratio and so is likely to contain more NO2 addition and peroxy-derived termination products. This cluster contains fewer fragmented species, as the average carbon number is higher and OSC‾ lower than cluster 2, and more species with an odd number of oxygen atoms. This suggests that clustering of time series which have features pertaining to distinct chemical regimes, for example, NO2/NOx perturbations, coupled with a priori knowledge, can provide insight into identification of potential functionality.

“…It has promising prospects based on strong oxidation performance and can decompose waste pollutants very well (Hassaan & Nemr, 2017;Paździor et al, 2019). Some of the AOPs techniques often used include the Fenton mechanism (Guo et al, 2018), photo-catalysis (Gilja et al, 2017), UV/H 2 O 2 (Malvestiti et al, 2019), and ozonation (Khamparia & Jaspal, 2017). However, the Fenton mechanism is an attractive alternative technology applied to batik cual wastewater treatment because it can be running at room temperature, decompose harmful non-biodegradable compounds, and does not require additional advanced equipment (M. H. Zhang et al, 2019).…”

During the production of batik cual, thick-colored wastewater is produced. Unfortunately, the wastewater could damage the environment if it is disposed of without specific processing. The Fenton method is an advanced oxidation process (AOPs) that can degrade organic dyes found in liquid waste. In this research, the researchers studied the Fenton mechanism's application to the batik cual wastewater treatment. The Fenton's reagent used was H2O2 with FeSO4.7H2O. Some of the experimental wastewater treatment parameters were the values of biological oxygen demand (BOD), chemical oxygen demand (COD), the degradation efficiency of difficult to decompose organic materials, and the color degradation efficiency in batik cual wastewater. The results show that the Fenton mechanism’s efficiency of removing color from batik cual wastewater is up to 97.8%, COD and BOD removal efficiencies are 76.3% and 75.2%, and the degradation efficiency of difficult to decompose organic matter is 76.8%. Also, the researchers found that the higher amounts of FeSO4.7H2O increase the removal parameters effectiveness. Therefore, the Fenton mechanism can effectively improve the quality of wastewater in batik cual production.

“…Many researchers are working on the treatment of wastewater generated from different industries like printing, dye [1], plastic, paint [2], textile [3], food, leather [4], petroleum [5], paper [6], cosmetics [7], distilleries [8], steel, rice mill, fractory nature [28][29][30]. For the treatment of generated wastewater, various conventional and non-conventional methods like coagulation method [31], biological method [32], ion exchange method have been used, but among these methods, advanced oxidation technology (AOTs) is very effective comparatively [16,33].…”

This comprehensive review focuses on the different factors, modification in the synthesis method, characterization and application of heterogeneous catalyst in the wastewater treatment based on the Fenton process. The present review highlights the different catalyst preparation methods like wet impregnation method, hydrothermal method, sol-gel method, precipitation method and their application to treat different recalcitrant organic chemicals. Major heterogeneous catalyst synthesis methods were discussed with their excellent workability. The importance of modification through physical and chemical method was also reported. Different catalyst, pollutants and optimum parametric conditions available in the literature along with some relevant studies are summarized. The effect of factors like pH, calcination and some other modifiers on the synthesis and their efficiency in the wastewater treatment has been described. The important characterization of synthesized catalysts explaining their working efficiency has also been discussed. In the final section, the application of heterogeneous catalyst synthesized by different methods in the wastewater/effluent treatment has been investigated. The main aim of this review is to find out the influence of process parameters and catalytic method on degradation/decolorization of organic compounds present in industrial or synthetic wastewater.
