GREEN SYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICALS USING DATES SEEDS (PHOENIX DACTYLIFERA L) EXTRACT FROM SIWA, EGYPT
Abstract
In the current study, silver nanoparticles (AgNPs) were biosynthesised
using Dates seeds (Phoenix dactylifera L) aqueous extract (LAE). HPLC
analysis was used to identify the chemical components, flavonoids and
phenolics, using both descriptive and quantitative analytics. Transmission
Electron Microscopy (TEM), Energy Dispersive X-Ray (EDX), Zeta
Potential, and FT-IR analysis were used to characterize the generated
powder of NPs. The chemicals that were most frequently identified in the
Dates seeds (Phoenix dactylifera L) .Extract by HPLC analysis were gallic
acid, chlorogenic acid, pyrocatechol, and methyl gallate. The AgNPs were
spherical in form and ranged in diameter from 8.70 nm to 13.4 nm. AgNPs
have charged potentials of -10.1 according to zeta potential. FTIR spectra
were used to characterize the hydroxyl functional group found in alcohols
and phenolic substances. This demonstrated that using dates seeds (Phoenix
dactylifera L) extract from the Siwa region of Egypt to create green silver
nanoparticles was successful
