A green synthetic route for the production of silver nanoparticles (AgNPs) using five different aqueous plant extracts, namely, Berberis vulgaris, Brassica nigra, Capsella bursapastoris, Lavandula angustifolia and Origanum vulgare, was investigated in this study. The present work demonstrates the influence of plant extract composition (antioxidant and total phenolic content) on the size and ...
PDF Synthesis of PlantMediated Silver Nanoparticles Using . Silver Nitrate ConcentrationsTo three test tubes containing 10 ml silver nitrate of different concentrations M, M and M, ml of plant extract was added with constant stirring and was observed for change in reaction mixture was then subjected to UVVis spectrophotometric analysis.
Extract of two organs of various plants were investigated in this research. The effect of the plant extract was determined by varying the concentration of plant extract in constant silver nitrate solution. To study the effect of temperature on nanoparticle synthesis, reaction mixtures containing plant extract,

· Synthesizing nanoparticles with the less environmentally malignant approach using plant extract is of great interest; this is because most of the chemical approaches can be very costly, toxic, and timeconsuming. Herein, we report the use of Acacia senegal leaf extracts to synthesize silver nanoparticles (AgNPs) using an environmentally greener approach.
The Silver Extraction Process. The ore used to extract silver was not a silver ore but Lead Sulphide (formula PbS), known as Galena or Galenite (named by the Roman Pliny) which contains 87% lead. The local variety of Galenite is silverbearing and is known as Argentiferous Galenite (formula ( ...
traction of silver from Ravanj flotation plant tailings were analyzed using statistics design of experiment and DX7 software; and it was determined that iron(III) sulfate concentration and temperature were the most effective factors on the extraction of silver. The results showed that the best
· Plantmediated synthesis of nanomaterials has been increasingly gaining popularity due to its ecofriendly nature and costeffectiveness. In the present study, we synthesized silver (Ag) nanoparticles using aqueous extracts of fresh leaves of Impatiens balsamina and Lantana camara medicinal plants as bioreducing agents.
A stock solution of plant aqueous extract was prepared by dissolving 100 mg of extract in 1 ml of sterile distilled water. Likewise, for the ethanol extract, 100 mg of extract was dissolved in 1 ml of 10 % Tween20 rather than the original solvent ( Dimethyl sulfoxide), and so the initial concentration of the plant extract (100 mg/ml)
silver concentration plant. When silver salt (AgNO3) is added to aqueous Neem leaf extract it results into a colour change from pale yellow to yellowish brown and finally to dark brown colour, as shown in Fig. 1. The change in colour of the solution is due to the presence of silver nanoparticles formed by the reduction of silver salt.
· The concentration of plant extract having different amount of phenolics and flavonoids, plays an essential role in the synthesis of stable AgNPs. We for the first time optimized the ratio of P. odorifer leaves extract to silver nitrate for the synthesis of AgNPs nanoparticles.
