Diospyros kaki leaf extract was used in this study as a favorable basis for the synthesis of copper nanoparticles (Cu NPs). X-ray diffraction (XRD) and UV-visible spectroscopy approaches were used to characterize the biologically synthesized copper nanoparticles. The XRD analysis showed that copper nanoparticles were face-centered cubic structure. Various experimental levels like conc. of dye, concentration of Cu NPs, pH, reaction time, and temperature were optimized to decolorize reactive red 81 dye using the synthesized Cu NPs. Reactive red 81 dye was decolorized maximum using Cu NPs of 0.005 mg/L. Additionally, reactive red 81 dye was decolorized at its maximum at pH = 6 , temperature = 50 ° C . Our study reported that chemical oxidation demand (COD) and total organic carbon (TOC) deduction efficacies were 74.56% and 73.24%. Further degradation study of reactive red 81 dye was also carried out. Cu NPs have the ability and promising potential to decolorize and degrade reactive red 81 dye found in wastewater.

he skin of the onion plant is a natural waste product. In this context, it is possible to evaluate their use in natural dyeing (cotton, wool, silk, etc.) and in lake pigment production by extracting the dyestuffs in these wastes. The skin that forms this outermost part contains some flavonoid (quercetin, etc.) and anthocyanidin (pelargonidin, etc.) natural dyestuffs. Quercetin glycosides are flavonoids liable for the majority of the flavonols in the plant. The amount of quercetin may increase from the inner part of the onion plant to the outer part. It is known that onion skin has been used in wool dyeing from past to present. It has traditionally been used in carpets and rugs. Onion skin was used in Anatolia, Turkey, where carpets and rugs were produced.

“…It was observed that maximum decolorization value was 95.76% at 40˚C (Figure 6b). In this treatment process, decolorization ability of Reactive Brown 9 dye slowly concentrated as the temperature increased (Rafique et al, 2021). There is a reduction in adsorption efficiency at higher temperatures, possibly because of the phase conversion of catalyst with temperature promotion, which may decay in the surface area of catalyst (Lafta, 2015).…”

“…COD and TOC reduction (%) values were found to be 88.56% and 85.34%, respectively at 50 minutes of contact time. Therefore, it may be expected that MgO nanoparticles not only get rid of color simply, but additionally lessen the COD and TOC of the dye solution to ensure mineralization progress (Kale and Kane, 2018;Kiran et al, 2020;Rafique et al, 2021).…”

<p>Nanotechnology is the newest and one of the most promising areas of research in modern medical sciences. Metal nanoparticles possess extraordinary optical, thermal, chemical properties and are being widely used in industrial, electronics, and biomedical fields. It has presented its potential to contribute to solving one of the greatest problems of the worldwide wastewater treatment issue. The approach of green synthesis of metal oxide nanoparticles seems to be a cost-efficient, eco-friendly, and easy alternative approach. The current study deals with the synthesis and characterization of Magnesium Oxide nanoparticles (MgO-NPs) using leaves extract of Iresine herbsti. The characterization was done by XRD and SEM. Then MgO-NPs were applied for the remediation of Reactive Brown 9 dye following the optimization of reaction parameters (conc. of dye, conc. of nanoparticles, pH, and temperature). The maximum decolorization (95.8%) was obtained at 0.02% dye conc., 0.003 mg/L conc. of MgO-NPs, at pH 4, and temperature 40 °C. TOC and COD were used for mineralization assessment of studied dye samples and their values were found to be 88.56% and 85.34%, respectively. The magnesium oxide nanoparticles could be applied successively for the treatment of other problematic dyes as well.</p>
