Biosynthesis of Copper Nanoparticles Using Aqueous Extracts of Aloe vera and Geranium and Bioleaching Solutions

Abstract:

Present work deals with synthesis of copper nanoparticles at the room temperature, using two aqueous extracts prepared from green and dry leaves of Aloe vera and Geranium (Pelargonium graveolens). Finely cut leaves were placed in the flask with the distilled water. The mixture was boiled for 15 min at the temperature of 60°C. After boiling, the mixture was centrifuged and pure extract was used for copper nanoparticles synthesis. The source of copper ions was leaching solution obtained from the bioleaching of copper shale (Kupferschiefier) using chemolithotrophic bacteria such as Acidithiobacillus frerooxidans. The bioleaching procedure was performed in the column reactor.
