[ 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 ] - تأثیر یون تارتارات بر رفتار جدایش روی و کادمیم در محلول سولفاتی
The aim of this study was to investigate the effect of tartrate ion (C4H4O62-) on the extraction and separation of zinc and cadmium using D2EHPA extractant. The presence of tartrate ion in the solution caused the shift of the extraction curve of zinc and cadmium to the more alkaline pH; however, the shifting rate for the cadmium extraction curve was more significant. In the absence of tartrat...
