“…Textile dyeing and finishing processes consume a significant amount of H 2 O and chemicals, generating a remarkably large amount of wastewater and making it the most polluting industrial effluent (Dantas et al 2006). Textile processing involves many different processes and the composition of wastewater depends greatly on the processes and chemicals used.…”

“…Besides, high dispersion and large surface area of some catalysts offer high degradation efficiency. Although the incorporation of catalyst makes oxidation reaction milder than classical Fenton process, it requires moderate temperature and pressure (Dantas et al 2006). …”

“…Heterogeneous catalysts that have been employed until now in AOPs include photocatalysts (TiO 2 ), ferrihydrite, α-Fe 2 O 3 , α-FeOOH, lepidocrocite (γ-FeOOH), magnetite, pyrite, and activated carbon (AC; Matta et al 2007, Rusevova et al 2012. The incorporation of transition metals on different supports such as Nafion, metals, AC, graphene, carbon aerogel, carbon nanotube (CNT), clays, polymers, alumina, fly ashes, and zeolite have been proven to have excellent catalytic activity in heterogeneous AOPs for wastewater treatment (Dantas et al 2006, Gonzalez-Olmos et al 2012. In heterogeneous reaction, the active phase is supported by porous matrices.…”

AbstractIn the past few years, there have been many researches on the use of different types of homogenous catalyst for the degradation of textile wastewater in conventional advanced oxidation processes (AOPs). However, homogenous AOPs suffer from few limitations, including large consumption of chemicals, acidic pH, high cost of hydrogen peroxide, generation of iron sludge, and necessity of post-treatment. Therefore, recently, there have been more researches that focus on improving the performance of conventional AOPs using heterogeneous catalysts such as titanium dioxide, nanomaterials, metal oxides, zeolite, hematite, goethite, magnetite, and activated carbon (AC). Besides, different supports such as AC that have been incorporated with transition metals and clays have been proven to have excellent catalytic activity in AOPs. This paper presents a comprehensive review of advances and prospects of catalytic AOPs for the decontamination of a wide range of synthetic and real textile wastewater. This review provides an up-to-date critical review of the information on the degradation of various textile dyes by a wide range of heterogeneous catalysts and adsorbents. The future challenges of AOPs, including chemical consumption, toxicity assessment, reactor design, and limitation of catalysts, are discussed in this paper. In addition, this paper also discusses the presence of ions, generation of by-products, and industrial applications of AOPs. Special emphasis is given to recent studies and large-scale combination of AOPs for wastewater treatment. This review paper concludes that more studies are needed for the kinetics, reactor design, and modeling of hybrid AOPs and the production of their corresponding intermediate products and secondary pollutants. A better economic model should also be developed to predict the cost of AOPs, as the treatment cost varies with dyes and textile effluents.

“…Zeolites [13][14][15][16][17], carbon materials [18,19], mesoporous and mixed oxides [20,21] and clays [12,[22][23][24][25][26] have been used as sup-ports of iron in the preparation of heterogeneous catalytic systems. In particular, zeolites containing transition metal ions have been shown to be promising solid-phase catalysts in the oxidation of a series of organic pollutants with hydrogen peroxide [27].…”

The degradation of Orange II dye (OII) by a heterogeneous Fenton-like process was studied using a catalyst with 5 wt.% of iron after ion-exchange in a Na-Y zeolite support. The catalyst was characterized by X-ray diffraction (XRD), N2 adsorption, atomic absorption spectroscopy and X-ray fluorescence (XRF). The effect of the initial concentrations of H2O2 and OII, pH and temperature on the degradation rate of OII was investigated by carrying out experiments in a batch reactor. The OII concentration histories (i.e., concentration evolution along reaction time) were described by a simple semi-empirical kinetic model, based on the Fermi's equation, which captures simultaneously the influence of all the reaction conditions with a few adjustable parameters. The adherence of the model to the data was remarkable, and the effect of the operating conditions on the obtained fitting parameters -apparent rate constant and transition timewas analyzed.2

“…Therefore, the catalysts were usually prepared in high surface area morphology or loaded on the materials with high surface area to form a highly dispersed status to enhance the contacting opportunity among the catalysts and reactants [13]. The treatment efficiency on textile wastewater using Fe 2 O 3 /carbon as the catalyst for heterogeneous Fenton reaction was studied [14]. The results showed that the composites with high Fe 2 O 3 content were effective to adsorb contaminants in textile wastewater, and the adsorptive capacity increased with the surficial iron concentration.…”

Iron based heterogeneous Fenton catalysts are attracting much attention for its economic and environmental friendly characteristics. In this study, iron oxides loaded carbon cloth (assigned as Fe@CC) was prepared using hydrothermal hydrolysis of Fe(NO 3 ) 3 . The specific surface area of Fe@CC determined by N 2 adsorption-desorption Brunauer-Emmett-Teller method was up to 1325.5 m 2 /g, which increased by 81.8% compared with that of native carbon cloth mainly due to the loading of iron oxide. XPS (X-ray photoelectron spectroscopy) spectra confirmed that the iron oxide on the carbon surface included mainly FeOOH. Its heterogeneous Fenton-like activity was determined using Acid Red G as a model substrate for degradation. Fe@CC maintained high and relatively stable activity during 11 tests, and it showed high COD (Chemical Oxygen Demand) removal efficiency and high apparent H 2 O 2 utilization efficiency. The homogeneous Fenton reaction using the amount of leached Fe(III) suggested that the surficial reaction on Fe@CC was dominant. The stability and the mechanism for gradual decrease of activity during the first 4 tests were also discussed.
