THE GREEN SYNTHESIS OF GOLD NANOPARTICLES USING THE ETHANOL EXTRACT OF BLACK TEA AND ITS TANNIN FREE FRACTION
Abstracts: nanoparticles. All the extracts were used separately for the synthesis of gold nanoparticles through the reduction ofaqueous AuClgold ions to gold nanoparticles. The ethanol extract of black tea and its tannin free ethanol extract produced goldnanoparticles in the size ranges of 2.5-27.5 nm and 1.25-17.5 nm with an average size of 10 nm and 3 nm, respectively.The prepared colloid gol...
متن کاملGreen Synthesis of Gold Nanoparticles Using Three Medicinal Plant Extracts as Efficient Reducing Agents
The aim of this work is a green synthesis of gold nanoparticles using the aqueous extract of Anthriscus sylvestris, Ferula gummosa, and Achillea eriohora leaf and stems as the reducing agents. The effects of reducing agent concentration in the reaction mixture and temperature on the size of the gold nanotriangles were studied. The nanoparticles were characterized using UV–Vis spectrosco...
