Eco-Friendly Production of Silver Nanoparticles from Peel of Tangerine for Degradation of Dye

Abstract

Green chemistry methods for production of nanoparticles have many advantages, such as ease of use, which makes the methods desirable and economically viable. The aim of the present work was to green synthesise silver nanoparticles (SNPs) using aqueous tangerine peel extract in different ratios (2:1, 1:1, 1:2). The formed SNPs were characterised using ultraviolet-visible (UV-Vis) spectrophotometry, and transmission electron microscopy (TEM). The UV-Vis spectra showed that the highest absorbance was observed when the ratio of peel tangerine extract to silver nitrate solution was 1:2. The transmission electron micrographs showed the formation of poly dispersed nanoparticles. It was found that the average diameter of the nanoparticles was 30.29 ± 5.1 nm, 16.68 ± 5.7 nm, and 25.85 ± 8.4 nm, using a tangerine peel solution and silver nitrate solution ratio of 2:1, 1:1, and 1:2, respectively. The formed SNPs were evaluated as catalysts for methyl orange dye degradation, and the results confirmed that SNPs can speed up the degradation of the dye.

Colorimetric Detection Based on Localized Surface Plasmon Resonance Optical Characteristics for Sensing of Mercury Using Green-Synthesized Silver Nanoparticles

“…Formation of Green AgNPs. For use in analytical applications, stable silver nanoparticles should be synthesized against the dilution, over ionic strength, different pH ranges, and long storage period [28,48,52]. In this study, wetchemical green synthesis was used for preparing the green silver nanoparticles because it constituted the most prevalent procedure for fabricating uniform nanoparticles with regulated sizes and strong silver nanoparticles alongside their colloidal dispersions in organic solvents or water [54][55][56].…”

“…Significant research attention in the development of mercury sensors has been accorded to AgNPs, particularly because of soft-soft chemistry involving sulfur with stabilizing ligands on AgNPs surfaces, thus changing the peak position and absorbance intensity, the presence of redox chemistry involving AgNPs (Ag°) and Hg 2+ leading to formation of Ag − Hg mixture through nanoparticle etching, high sensitivity of AgNPs localized surface plasmon resonances, and cost-effective synthesis [2]. Besides, a UV − Vis spectrophotometer containing specific optical properties and which use LSPRs within the visibility range of 350-800 nm can be used for easy monitoring of AgNPs [26][27][28][29][30][31]. Radiation chemical reductions [32], photo reduction within reverse micelles [33], and chemical stabilisation with reagents, including sodium borohydride, ascorbate, and sodium citrate [34][35][36][37] have been used for synthesizing silver nanoparticles.…”
