The development of new strategies and photocatalytic materials for practical environmental solutions remains a great challenge, particularly due to the large energy demands associated with various remediation processes. In this paper, we report the fabrication of self-assembled ordered mesoporous TiO2 with highly crystalline anatase structures as well as high surface area, and characterize thei...

Magnetic porous microspheres are widely used in modern wastewater treatment technology due to their simple and quick dye adsorption and separation functions. In this article, we prepared porous polymethylmethacrylate (PMMA) microspheres by the seed-swelling method, followed by in situ formation of iron oxide (Fe₃O₄) nanoparticles within the pore. Then, we used diazo-resin (DR) to encapsulate th...

This study utilized Swietenia mahagoni bark–a wood processing industry waste, for the preparation of activated carbon, and then investigated for the removal of methyl orange (MO) dye by the Swietenia mahagoni bark activated carbon (SMBAC). The effect of pH (3–10), adsorbent dose (1–30 g/L), initial MO dye concentration (10–100 mg/L), and contact time (1–240 min) were evaluated...

Abstract Natural mulberry leaves and carboxylic acid-modified (Morus alba L.) were used for the first time to scrutinize effects of modification on retention efficiency an anionic dye (Remazol Brilliant Blue R (RBBR)) from aqueous solutions suggest economical promising adsorbent treatment dye-contaminated water. The characterization adsorbents was accomplished through common techniques includin...

Magnetic NiFe2O4 nanoparticle (NFNPs) were synthesized by the microwave-assisted method using Tamarindus indica seeds as a green reducing agent’ for better readability. The identification of NFNPs was carried out X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) with energy dispersive analysis (EDX), transmission microscopy (TEM),...

Abstract The hydrogen peroxide role in photocatalytic degradation of an anionic azo dye, Acid Orange 7 (AO7), was investigated a slurry reactor. Commercial ZnO nanoparticles with average size between 10 to 30 nm were used as catalysts. Optimum conditions for different parameters, including dye concentration (10–100 mg/L), catalyst (0.1–0.5 g/L), and pH (5–10), determined first the absence H2O2....

In this study, the properties and adsorption behaviors of organoclays synthesized with two structurally different surfactants having same carbon chain length (hexadecyltrimethylammonium bromide (HDTMAB) benzyldimethylhexadecylammonium chloride (BDHAC)) were evaluated. The structural examined using Fourier-transform infrared spectroscopy, zeta potential analysis, X-ray diffraction, N2 adsorption...
