“…A primary characteristic of Azoic dyes is the unique N = N chromophoric units whiles that of Xanthene is the yellow solid organic compound with the formula CH 2 [C 6 H 4 ] 2 O that is soluble in common organic solvents (Benkhaya et al, 2020). With the textile industry having about 60-70% usage of all available commercial dye products (Saggioro et al, 2011), the dye pollutants from these industries tend to contaminate the environment especially water bodies; when they are indecorously disposed-of (Habib et al, 2013;Rahman et al, 2014;Rezig & Hadjel, 2014). Furthermore, recent advances in environmental remediation strategies such as photocatalysis and flocculation have been researched as an alternative technique for purification of dye-polluted water (Agbe et al, 2018;Diko et al, 2020).…”

Synthesis of nanostructured cupric oxide for visible light assisted degradation of organic wastewater pollutants

When organic dye-containing wastewater from textile industries are sometimes released into the environment, the liquids tend to pollute the environment whilst their solid residue accrues on land after the evaporation of the water. Most of these synthetic compounds are known to be poisonous and carcinogenic to living organisms. For this study, a relatively simple, sustainable and cost-effective approach have been utilized to synthesize CuO nanoparticles using copper precursor salts: (CuSO 4 .5H 2 O) and (Cu(NO 3 ) 2 .3H 2 O), as a remedy for dye pollution reduction in water. Due to their simplicity of synthesis, insignificant harmfulness and cost, copper (II) oxide (CuO) nanoparticles were used to breakdown three generally utilized dyes; Rhodamine B (RhB), Methylene Blue (MB)-[Methylthioninium chloride] and Methyl Orange (MeO). The as-prepared nanoparticles were characterized to

“…These on-going waste disposal processes tend to compromise the quality of water for daily use despite the great importance of clean water to society [ 1 , 2 , 3 ]. Dye pollutants from the textile, dye, food, leather and paper industries, among others, contaminate the environment when they are improperly disposed-of [ 4 , 5 , 6 , 7 , 8 ]. Yet these synthetic polymeric dyes have a wide spectrum of applications, which makes their use inevitable.…”

Nanostructured mesoporous titanium dioxide (TiO2) particles with high specific surface area and average crystallite domain sizes within 2 nm and 30 nm have been prepared via the sol-gel and hydrothermal procedures. The characteristics of produced nanoparticles have been tested using X-Ray Diffraction (XRD), Brunauer–Emmett–Teller (BET) surface area analysis, Scanning Electron Microscopy (SEM), Fourier Transform Infra-Red (FTIR), and Raman Spectroscopy as a function of temperature for their microstructural, porosity, morphological, structural and absorption properties. The as-synthesized TiO2 nanostructures were attempted as catalysts in Rhodamine B and Sudan III dyes' photocatalytic decomposition in a batch reactor with the assistance of Ultra Violet (UV) light. The results show that for catalysts calcined at 300 °C, ∼100 % decomposition of Sudan III dye was observed when Hydrothermal based catalyst was used whiles ∼94 % decomposition of Rhodamine B dye was observed using the sol-gel based catalysts. These synthesized TiO2 nanoparticles have promising potential applications in the light aided decomposition of a wide range of dye pollutants.

“…Various techniques have been developed for the immobilization of TiO 2 on a solid substrate including dip coating suspension [5,6], spray coating and sol-gel. Moreover, different types of substrates were tested such as glass beads [7], glass tubes [8], fiber glass [9], quartz [10], stainless steel [11], aluminum [12], activated carbon [13], silica [14] and glass plates [15] and modified diatomite [16,17]. It is worth noting that fresh water supply is currently under pressure due to rapid population growth and therefore reuse of wastewater effluent is rapidly growing and becoming a necessity for water utilities.…”

A B S T R A C TThe aim of this work was to study the photocatalytic degradation of Methylene Blue and phenol by nano-particles coated on diatomite as a new nano-composite catalyst. Titanium dioxide (Degussa P25) was immobilized on diatomite powder at different compositions by a very simple and low cost technique. Diatomite powder (also called Kieselguhr) is an Algerian substance with a snow-white color and porosity greater than 72%. High porosity allowed the diatomite powder to float on the surface of water providing a means for the treatment process that enabled separation from water without any need for pumping as well as the exposure to solar radiation when supported beneath titanium dioxide (TiO 2 ) during photocatalysis. The morphology characterization of the prepared catalysts was carried out by X-ray diffraction analysis, scanning electron microscopy and infrared spectroscopy (IR). Photocatalytic activity was initially tested in a single reactor followed by pH, conductivity and absorbance analyses. Photocatalytic treatment of synthetically polluted water with Methylene Blue and phenol showed good performance for the two new nano-composites using immobilized TiO 2 on diatomite.
