“…Organic and synthetic dyes, the contaminant effluents cleared from different food and fabric industries, are one of the key sources of environmental contamination owed to their non-biodegradable behavior 2 . The enormous amount of industrialized organic dyes is discharged by the textile industry into waterways and other water resources, which eventually spoil water quality 3 . The vast majority of the manufactured dyes contain complex structures having azo groups, exhibit serious harmfulness when breathed in utilizing drinking dyecontaminated water, which in the end causes cancers of various portions of the human body 4 .…”

The adsorption behavior of Bismarck brown (BB) dye from aqueous solutions onto graphene oxide GO and graphene oxide-g-poly (n-butyl methacrylate-co-methacrylic acid) GO-g-pBCM as adsorbents was investigated. The prepared GO and GO-g-pBCM were characterized by Fourier transform infrared spectroscopy FTIR, which confirmed the compositions of the prepared adsorbents. Adsorption of BB dye onto GO and GO-g-pBCM was explored in a series of batch experiments under various conditions. The data were examined utilizing Langmuir and Freundlich isotherms. The Langmuir isotherm was seen as increasingly reasonable from the experimental information of dye on formulating adsorbents. Kinetic investigations showed that the experimental data were fitted very well to the pseudo-second-order model, and the calculated positive values of the (∆H° and ∆S°) indicated that the adsorption of BB dye onto GO and GO-g-pBCM was endothermic and increasing of the adsorption process randomness. The negative values of (∆G°) imply that the adsorption process was spontaneous.

“…Apart from these, phytochemicals also have other positive impacts on NMs such as low particle size, high surface area, and low toxicity of particles. So far, many NMs have been prepared via a green method (either using plant extract otherwise) and applied to wastewater treatment [8,9].…”

“…At present, the use of metal tungstate (MWO 4 ) in wastewater treatment is considered very useful. Several types of MWO 4, such as M = Co [10], Cd [8], Zn [11], and Cu [12], have been shown to act as photocatalysts, with CdWO 4 being predominant [8]. Virgin CdWO 4 photocatalyst has been used for the degradation of dyes such as CR and methyl orange [13].…”

This study reports the synthesis of copper–zinc binary oxide coupled cadmium tungstate through a simple bio-precipitation method followed by calcination at 600 °C and its adsorption application. The characterization analysis reveals that the prepared composite has low particles size (nano-range), high porosity, and functional groups on the surface. The calcination of sample at 600 °C causes some essential function groups to disappear on the surface. Prepared composite was found to be effective adsorptive material to treat Congo red dye in aqueous solution. 2.5 g L−1 dose of adsorbent could remove more than 99% Congo red dye from 10 mg L−1 solution and more than 80% Congo red dye from 60 mg L−1 aqueous solution. The maximum adsorption capacity of present adsorbent was calculated to be 19.6 mg Congo red per gram of adsorbent. Isotherms analysis suggested a physio-chemical adsorption process. Thermodynamic analysis revealed a exothermic and feasible adsorption process. Adsorption rate was well explained by pseudo second order kinetics. The rate determining step was intra-particle diffusion evaluated from the Weber-Morris plot. To assess the adsorption performance of present adsorbent for Congo red dye the partition coefficient and adsorption equilibrium capacity were compared with other adsorbents. The partition coefficient and adsorption equilibrium values for 10 mg L−1 aqueous solution were found to be approximately 83.3 mg g−1 µM−1 and 4.0 mg g−1 at 30 °C and 7.0 pH using 2.5 g L−1 adsorbent. The value of partition coefficient was found to be higher than previous reported zinc oxide coupled cadmium tungstate having partition coefficient = as 21.4 mg g−1 µM−1 at 30 °C and 7.0 pH using 2.0 g L−1 adsorbent. These results suggested that present adsorption technology is efficient for wastewater treatment.

“…After that, the holes and electrons generate hydroxy free radicals (OH . ) that has an excellent ability to degrade the organic dyes [25][26][27]. There are a limited number of photocatalysts that degrade orange G dye such as zinc phthalocyanine-cobalt ferrite, ZnO/activated carbon nanocomposite, and ZnO/TiO 2 composite [28][29][30].…”

In this work, MgO nanoparticles were synthesized via the combustion method using glutamine and L-arginine as fuels for the first time. Also, the synthesized MgO products were identified utilizing FT-IR, XRD, HR-TEM, FE-SEM, UV-Vis, and PL techniques. Besides, the synthesized MgO samples were used for the photochemical degradation of orange G dye as well as biological activity against some bacterial (Staphylococcus aureus and Escherichia coli) and fungal (Candida albicans and Aspergillus flavus) strains. The XRD confirmed that the average crystallite size of MgO products, which were produced using glutamine and L-arginine fuels, is 35.19 and 26.45 nm, respectively. Also, The FE-SEM images confirmed that the MgO products, which were produced using glutamine and L-arginine fuels, is comprised of irregular and flaky shapes with an average size of 13.16 and 9.02 µm, respectively. Additionally, the greatest percent of degradation of orange G dye was 92.30 and 96.60% after 120 min using the MgO samples which were synthesized using glutamine and L-arginine fuels, respectively. Furthermore, the MgO samples show moderate biological activity against bacterial strains whereas they show no biological activity against fungal strains.
