Abstract
Nanoparticles are known to be of wide applications in various fields of human endeavours. Many methods of syntheses such as physical, chemical are harmful to the environment, thus, this study utilised green production of nanoparticles via waste product such as Citrulus vulgaris seed. Oil was extracted using soxhlet extractor from the prepared Citrulus vulgaris seed. Physico-chemical properties such as percentage yield, acid value, peroxide value were carried out on the Citrulus vulgaris seed oil. Citrulus vulgaris was further processed to form lecithin. The lecithin extracted was characterized for colour, Peroxide Value, Acetone Insoluble (AI), Acid Value, solubility in water and organic solvents. The result of the physico-chemical parameters was in conformity with the standard and various literatures. Therefore, lecithin is processed into dispersed aqueous silver nanoparticles by the addition of silver nitrate. The chemical reaction was monitored progressively using visual assessment, UV-visible and FTIR Spectroscopy. The size and surface of the dispersed silver nanoparticles produced was analysed using Atomic Force Microscopy. Therefore, a dispersed aqueous silver nanoparticle was produced from lecithin made from Citrulus vulgaris seed oil.
Highlights
The nanoparticles are small particles that range between 1 to 100 nanometres in size
According to Hoshyar, et al, 2016; Kamala et al, 2020 [3, 4], at the introduction of light energy, noble metal nanoparticles show wavelength selective photon absorption and huge enhancement in local electric fields, due to a phenomenon known as surface plasmon resonance (SPR), which forms the basis of their diverse applications
A Few research study available on Citrullus vulgaris were mostly on proximate and nutritional values [18], this paper examined the feasibility of synthesizing stable aqueous dispersion of Silver nanoparticles using Citrulus vulgaris seed oil as a feedstock
Summary
The nanoparticles are small particles that range between 1 to 100 nanometres in size. According to Gidigbi, et al, 2019 [13], the quest to annex a renewable source of raw materials and to address the ever-increasing pollution in the society, mostly created by unit process and unit operation of an industrial activities, necessitates research into plant materials, especially to leverage on its numerous nutritional and industrial applications. A Few research study available on Citrullus vulgaris were mostly on proximate and nutritional values [18], this paper examined the feasibility of synthesizing stable aqueous dispersion of Silver nanoparticles using Citrulus vulgaris seed oil as a feedstock
