“…1) is a prominent acidic dye in the textile industry, having different applications, such as dyeing of cotton and leather and production of printer cartridges and rubber stamps. This dye belongs to the class of xanthenes and is of difficult discoloration, has red color, is fluorescent and, as well as other dyes, poses risks to the environment and humans (Macedo 2012;Salgado and Paulino 2013;Wang et al 2014). Thus, it is interesting to look for efficient ways for the discoloration of textile dyes.…”

“…The complexity of the composition of textile effluents, as well as the presence of nonbiodegradable and carcinogenic contaminants, hamper the treatment by conventional methods, such as biological degradation, physical adsorption, and flocculation (Tisa et al 2014). The latter ones do not destroy organic contaminants, only transfer them from the aqueous to the solid phase (Verma et al 2012;Li et al 2013;Wang et al 2014).…”

“…Advanced oxidation processes (AOPs) have been widely studied for the degradation of persistent organic contaminants present in water (Pereira et al 2012;Li et al 2013;Tisa et al 2014;Wang et al 2014;Silva et al 2016). This technology is characterized by the generation of the hydroxyl radical (HO • ), which has a high standard reduction potential (E 0 = 2.8 V), and therefore, it is able to oxidize organic contaminants to their mineralization (Marmitt et al 2010;Wang et al 2014).…”

AOPs consist of different processes that generate the hydroxyl radical, among which the following stand out: photolysis (UV/ H 2 O 2 ), Fenton (Fe 2+ /H 2 O 2 ), photo-Fenton (UV/Fe 2+ / H 2 O 2 ), photocatalysis (UV/Fe 2+ /H 2 O 2 ), and ozonolysis (UV/O 3 ) (Amorim et al 2009;Tisa et al 2014;Pereira et al 2012).…”

In this study, the oxidation of the dye rhodamine B (RhB), present in a synthetic effluent, and the degradation of organic matter present in a textile effluent, were assessed by photolysis (HO, UV), homogeneous Fenton (Fe, HO), and photocatalysis (TiO, UV). The results showed that photolysis and Fenton had an efficiency of 100 % and photocatalysis, 96 %, to discoloration 10 mg L RhB, present in the synthetic effluent. The best experimental conditions determined for these reactions showed that the one performed with 51 mg L HO and UV light had the best results, where 100 % of RhB was discolored in only 6 min of reaction. The optimum conditions determined in the first part of this study for the RhB oxidation did not show satisfactory results for the degradation of organic matter present in the textile effluent sample, and it was necessary to increase the amount of reagents in the three processes. After resizing the concentration of the reagents for the reactions with the textile effluent, the following reductions of color, total organic carbon (TOC), and total soluble solids (SS) were obtained: photocatalysis 29, 25, and 32 %; photolysis 85, 69, and 35 %; Fenton 98, 90, and 23 %; and biological (followed by physicochemical) treatment carried out by the textile industry 96, 48, and 9 %. It is observed that the Fenton reaction showed the best result, followed by photolysis reaction, a treatment carried out by industry and, at last, photocatalysis.

Boron doped hematite catalysts 10%B-90% α-Fe 2 O 3 (10BH) and 5%B-95% α-Fe 2 O 3 (5BH) were synthesized and characterized using XRD, BET and SEM techniques. Central composite design (CCD) matrix and response surface methodology (RSM) were applied to design experiments for evaluating the interactive effects of four operating variables [peroxide dosage (600-1200 mg/l), catalyst dosage (10-50 mg/l), pH (3-8), and reaction time (10-300 mins)] on the percentage COD reduction of tannery wastewater with initial COD of 1200 mg/l. RSM showed that the BH catalyst had better percentage COD reduction of 83% at optimum parameter values of 600 mg/l, 35 mg/l, 8 and 90 minutes for peroxide dosage, catalyst dosage, pH and time respectively. 71% COD reduction was achieved with the 5BH catalyst at optimum parameter values of 600 mg/l, 35 mg/l, 8 and 90 minutes for peroxide dosage, catalyst dosage, pH and time respectively. This study clearly showed that boron doping increased the catalytic activity of hematite as a catalyst in the Fenton oxidation system.

Cost‐Effective H₂O₂‐Regeneration of Powdered Activated Carbon by Isolated Fe Sites

The reuse of powdered activated carbon (PAC) vitally determines the economics and security of the PAC‐based adsorption process, while state‐of‐the‐art PAC regeneration technologies are usually unsatisfactory. Here, it is demonstrated that isolated Fe sites anchored on commercial PAC enable fast H2O2 activation to produce Fe‐based reactive oxygen species for highly efficient PAC regeneration at room temperature. Taking rhodamine B as a representative pollutant, PAC decorated with isolated Fe sites realize H2O2 based regeneration with negligible adsorption capacity degradation for 10 cycles. Moreover, in terms of the PAC loss rate, this technology is greatly superior to traditional Fenton‐based regeneration technology. Further operando experiments and theoretical calculations reveal that the high regeneration performance can be attributed to the isolated HOFeO motifs, which activate H2O2 via a nonradical reaction pathway. These findings provide a very promising strategy toward reducing the cost of H2O2‐based PAC regeneration technology.
