[ 1 ] - Extraction of Ni and Co via D2EHPA in the Presence of Acetate Ion
The effect of acetate ion introduced to aqueous solutions was investigated for the extraction/separation of Ni and Co from a dilute sulfate media. The separation of Co and Ni was improved by introducing acetate to aqueous media. By the use of the slope analysis method,the stoichiometric coefficient of the extractant was found to be 4 for cobalt and 3.5 or 4 for nickel depending on the aceta...
[ 2 ] - پلیال، روشی قابل تنظیم برای سنتز نانوساختارهای صفربعدی و تکبعدی نقره و آلیاژ نقره- مس
In this study, null and one-dimensional nanoparticles and nanostructures of Ag and Ag-Cu were synthesized using polyol method. In order to prepare different nanostructures with the same synthesis route, thermodynamics and kinetic conditions of the system were manipulated. In the thermodynamics approach, the nanostructures with the minimum surface energy were obtained as the final product, while...
