An investigation of the optimal conditions for the green syn-2 thesis of silver nanoparticles using an aqueous extract from the 3 plant Agrimonia eupatoria L.

Abstract

In this research study, silver nitrate and an aqueous extract of the Agrimonia eupatoria L. plant were used for the synthesis of silver nanoparticles (AgNPs). The optimal conditions for this green synthesis were examined: the concentration of starting substances, pH value, and temperature. For the maximum AgNP yield, the best conditions were a 5 mM AgNO3 concentration, 1% extract concentration, a temperature of 25 °C, pH = 6, and a 3 h reaction time.
