We reported the simultaneous decolorization of tartrazine and H2 production via electrocoagulation photocatalysis using CuO-doped TiO2 nanotube arrays (TNTA) composites. Tartrazine was removed by combination adsorption, electrocoagulation, photocatalytic degradation, while produced through water reduction at cathode splitting process on photocatalyst surface. The photoreactor contains CuO-TNTA ...

A facial one-step synthesis procedure was applied to prepare porous sponge-like ceria (CeO2). The performed by mixing cerium nitrate with citric acid, followed thermal treatment. produced solid material characterized several techniques, such as XRD, SEM, N2 sorption measurement, DR-UV-vis, and Raman spectroscopy. characterization data showed that the nanoparticles of were formed a three-dimensi...

This work studied the potential use of horseradish peroxidase (HRP) in the decolorization of the following textile dyes: Drimarene Blue X-3LR (DMBLR), Drimarene Blue X-BLN (DMBBLN), Drimarene Rubinol X-3LR (DMR), and Drimarene Blue CL-R (RBBR). Dyes were individually tested in the reaction media containing 120 mg·L(-1), considering the following parameters: temperature (20-45°C), H(2)O(2) conce...

A thin wetted film cylindrical flow reactor was fabricated for photocatalytic oxidation of Procion blue H-B dye in textile washwater with the suspensions of TiO2 and ZnO. The disappearance of colour and organic reduction were studied in terms of the removal of colour and chemical oxygen demand (COD). Operating parameters such as effect of pH, UV irradiation with and without catalyst, initial co...

Myrothecium verrucaria 3.2190 is a nonligninolytic fungus that produces bilirubin oxidase. Both M. verrucaria and the extracellular bilirubin oxidase were tested for their ability to decolorize indigo carmine. The biosorption and biodegradation of the dye were detected during the process of decolorization; more than 98% decolorization efficiency was achieved after 7 days at 26°C. Additionally, ...

The biodegradation of synthetic dyes by fungi is emerging as an effective and promising approach. In the present study, freshwater fungal strains isolated from submerged woods were screened for the decolorization of 7 synthetic dyes. Subsequently, 13 isolates with high decolorization capability were assessed in a liquid system; they belonged to 9 different fungal species. Several strains exhibi...

The aim of this study was to investigate the feasibility of two decontaminating processes, ozonation and electrocoagulation, to decolorize wastewater generated by humid finishing leather production. With the objective to determine if one or both process could remove color, benchscale experiments were conducted with three different colorants, representative of the main dye groups: di-azo (CI Dir...

In this study, the optimization of working cathode position in sleeve-type bioelectrochemical system (BES) was evaluated with inner/outer chamber for azo dye decolorization. Results showed that the working position in outer chamber performed better with decolorization efficiencies of 97.8 ± 2.1% (7h) and 94.0 ± 2.3% (16 h) than that in inner chamber as the volume ratio Vcathode:Vanode=1:1 and 3...

Abstract In the present study, zinc oxide (ZnO), gold (Au) and doped (Au-ZnO) nanoparticles (NPs) were successfully synthesized through thermal decomposition of [Au(L)Cl]Cl.H 2 O [Zn(L) ].H complexes, where L is 7-[2-(BenzImidazolyl) Azo]-8-Hydroxy Quinoline (BIAHQ). Several characterization techniques such as XRD, FT-IR), UV–Vis DRS, SEM, TEM, AFM) employed to investigate phase structure, crys...
