Research paper thumbnail of Process Parameters for Green Synthesis of Silver Nanoparticles using Leaves Extract of Aloe Vera Plant 31 PUBLICATIONS 6 CITATIONS SEE PROFILE Process Parameters for Green Synthesis of Silver Nanoparticles using Leaves Extract of Aloe Vera Plant

The formation of AgNPs was confirmed by changing their color to dark brown due to surface plasmon resonance (SPR) phenomenon. The effect of process parameters on synthesis of AgNPs from Aloe Vera leaves extract such as AgNO 3 concentration (molarity), extract volume percent, sunlight exposure time and temperature were studied. The AgNPs obtained were characterized using UV-vis spectroscopy, Atomic Absorption Spectroscopy (AAS), Atomic force microscopy (AFM), and Fourier Transformation Infrared Spectroscopy (FTIR). UV-Vis spectroscopy showed the SPR peaks for AgNPs using Aloe Vera leaves extract were between 420-490 nm. Atomic force microscopy (AFM) showed the AgNPs are spherical in shapes with the average particle diameters between 34-102 nm. The best conditions for synthesis of AgNPs using Aloe Vera leaves extract were found at 5 mM AgNO 3 concentration, 15% extract volume percent, for 10 min of sunlight exposure and temperature at 60 o C.

In this present study spent tea leaves extract was used synthesizing of AgNPs. Synthesizing of AgNPs was confirmed by changing their color to dark brown due to surface plasmon resonance (SPR) phenomenon. Process parameters such as AgNO3 concentration (molarity), extract volume percent, sunlight exposure time and temperature were studied. UV-Vis spectroscopy showed the SPR peaks for AgNPs were between370-435 nm using spent tea leaves extract. Atomic force microscopy (AFM) showed the average particle diameters of AgNPs were between 66-117 nm using spent tea leaves extract. Atomic Absorption Spectroscopy (AAS) showed the maximum extraction efficiency was 47% using spent tea extract.
