“…The reductions in COD, TOC and BOD values after treatment of textile real wastewater revealed that immobilized ZnO over PUF is efficient to treat the wastewater containing textile dyes, which are otherwise difficult to treat. Under the current scenario of environmental pollution [6,[14][15][16][57][58][59][60][61][62], there is need to develop and utilize efficient materials that are active under solar light and ZnO/PUF proved to be highly efficient since the activity was considerable under solar light that could possibly be used for the degradation of dyes in textile wastewater [63][64][65][66][67].…”

Zinc oxide (ZnO) nanoparticles were immobilized on polyurethane foam (PUF) and employed for the degradation of Acid black 1 dye (AB1). The ZnO/PUF was characterized by x-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive x-ray (EDX) techniques. Process variables i.e., dye concentration, pH, concentration of H 2 O 2 , irradiation time were optimized for maximum degradation of dye. ZnO/PUF showed promising efficiency for the degradation of AB1 dye and up to 86% and 65% dye degradation was achieved under UV and solar light irradiation at neutral pH, 4% H 2 O 2 , 240 min/sunlight and 75 min/UV irradiation time using 40 mg l −1 dye initial concentration. The optimum conditions were applied for the treatment of textile wastewater and biological oxygen demand (BOD) and total organic carbon (TOC) were reduced up to 70% and 80%, respectively. In view of promising photocatalytic activity (PCA), ZnO/PUF could possibly be used for the treatment of wastewater contains dyes.

“…The conventional methods, including chemical methods (such as electrochemical and chemical precipitation), physical methods (such as adsorption), and biological methods are not effective in the eradication of the pesticide pollutants from the environment. Therefore, advanced methods are needed for the treatment of pesticide-contaminated water [7,15]. Techniques known as advanced oxidation processes (AOPs) are considered effective strategies for the complete remediation of the agrochemicals present in water.…”

The excessive use of pesticides has led to the harmful contamination of water reservoirs. Visible-light-driven photocatalysis is one of the suitable methods for the removal of pesticides from water. Herein, the development of CBO (Co3O4-Bi2O3) as a heterogeneous catalyst for the visible light-assisted degradation of Fipronil and Acetochlor pesticides is reported. After synthesis via coprecipitation using cobalt (II) nitrate hexahydrate (Co(NO3)2·6H2O), bismuth (III) nitrate pentahydrate (Bi(NO3)3·5H2O) and sodium hydroxide (NaOH) as precursor materials, the prepared CBO was characterized using advanced techniques including XRD, EDS, TEM, SEM, FTIR, and surface area and pore size analysis. Then, it was employed as a photocatalyst for the degradation of Fipronil and Acetochlor pesticides under visible light irradiation. The complete removal of Fipronil and Acetochlor pesticides was observed over CBO photocatalyst using 50 mL (100 mg/L) of each pesticide separately within 120 min of reaction. The reaction kinetics was investigated using a non-linear method of analysis using the Solver add-in. The prepared CBO exhibited a 2.8-fold and 2-fold catalytic performance in the photodegradation of selected pesticides than Co3O4 and Bi2O3 did, respectively.

Textile and other dye house effluents from different industries have many worst effects on aquatic as well as non-aquatic life. The present work was carried out for the conditions optimization of degradation of Allura Red AC dye. This was done by UV treatment and examining the effects of different parameters on degradation i.e. pH, concentration of the dye, temperature, radiation exposure time and concentration of TiO 2 . The efficiency of the treatment was monitored by checking the highest degradation value, parameters of water quality such as chemical oxygen demand (COD), biological oxygen demand (BOD) and toxicity. The end products of degradation of dye were checked out by UV/visible spectrophotometer, Fourier transform-infra red (FT-IR) and gas chromatographymass spectrometry (GC-MS) techniques. From the results, it was concluded that the degradation efficiency was in the order UV/H 2 O 2 /TiO 2 > UV/H 2 O 2 > UV alone. Furthermore, it was also concluded that UV/H 2 O 2 /TiO 2 could be implemented on industrial scale for the removal of the toxic pollutants from industrial effluents.
