2.3.5. Concentration ratio of silver nitrate and leaf extract
The above mentioned procedure was also repeated for optimization
of silver nitrate and leaf extract concentration required
for the maximum production of silver nanoparticles, where the
reaction was monitored by using different ratio of silver nitrate
and leaf extract solution (0.5:19.5, 1.5:20, 1:19, 2:20 and 2:25).
The absorbance of the resulting solutions was measured
spectrophotometrically.
