Photodegradation of Biohazardous Dye Brilliant Blue R Using Organometallic Silver Nanoparticles Synthesized through a Green Chemistry Method

Abstract

Nowadays, nanostructures having tremendous chemical and physical properties are gaining attention in the biomedical industry. However, when they are prepared through classical methods (physical and chemical), they are often non-biocompatible and toxic. Considering the mentioned factors, in this research, organometallic silver nanostructures (OMAgNs) have been prepared by the green chemistry method using the acetone, methanol, and methanol-hexane-based extracts of the medicinally important plant Cichorium intybus. Secondary metabolites from C. intybus can be used as an alternative to synthetic reagents at an industrial scale to manufacture biosafe and economical nanostructures with enhanced physicochemical parameters. Prepared nanostructures were characterized using SEM, XRD, FTIR, TGA, UV, and zeta potential measurement. SEM analysis revealed different shapes of OMAgNs, prepared with various extracts. XRD analysis showed the crystallinity of the nanostructures. FTIR spectroscopy helped to identify groups of compounds present in the extracts and used for the OMAgNs synthesis. Out of the three tested OMAgNs, those prepared with methanol extract were selected due to the highest obtained yield and stability (highest negative zeta potential) and were tested as a cost-efficient and active agent to photodegrade organic pollutant, Brilliant Blue R, using energy from sunlight. A decrease in UV-VIS absorbance confirmed the rapid degradation of the dye.

“… 34 Moreover, the X-ray emission from the enzymes and proteins present in the aqueous extract of H. sabdariffa flowers resulted in the detection of other elements as silicon, chlorine, carbon, and oxygen. 35 In addition, the abundance of chlorine (Cl − ) ions in plants, which were found to be responsible for maintaining homeostasis and playing a crucial role during photosynthesis, was signified by other researchers as the reason for the strong peak of Cl− detected by EDX spectrum of the biogenic AgNPs. 36 Communally, the odd elements as Si, and Cl apprehended by EDX elemental configuration were reported to be crucial for the bioreduction of Ag + ions to synthesize elemental silver (Ag 0 ), as well as for capping and stabilizing the biosynthesized AgNPs.…”

Prospects of Nanotechnology in Improving the Productivity and Quality of Horticultural Crops

“…Kasaai [104] found that the incorporation of nano-Si as a surface coating in food packaging increases the quality and storage ability of horticultural crops. Ag-NPs coated packaging materials can lessen the microbial activity, leading to an increase shelf-life of food materials [105]. Besides, Ag-NPs, ZnO-NPs, TiO 2 -NPs, MgO-Nps, CuO, chitosan nanoparticles, carbon nanotubes, quantum dots, etc., are commercially very important for improving the quality and shelf-life of storage fruits, vegetables and exporting foods, since these NPs have anti-microbial activity [102,[106][107][108].…”

“…The inclusion of Ag-nanostructures in coating organic polymers augmented the mechanical properties of coating films [115]. Like India, China is also widely applying Ag-NPs to boost the storage and freshness of fruits and vegetables [105]. Owing to the significant antimicrobial characteristics of Ag-NPs, the shelf-life of cherry tomatoes can be enhanced by up to 15 days.…”
