چکیده

در این تحقیق استخراج انتخابی مس از نیکل در حضور افزودنی‌هایی مانند اسید تارتاریک و استات سدیم با D2EHPA مطالعه شد. برای بررسی رفتار کربوکسیلات‌ها بر جدایش مس از نیکل پارامترهای pH، غلظت کربوکسیلات­ها و زمان بررسی شد. طبق نتایج بدست آمده. ، با افزودن 04/0 گرم بر لیتر استات سدیم و 03/0 گرم بر لیتر اسید تارتاریک در زمان 10 دقیقه و در 12/5 pH=، 90% مس و 20% نیکل استخراج می‌شود. فاکتور جدایش در این حالت به بیشترین مقدار یعنی 75/25 رسید. بنابراین، اختلاط اسید تارتاریک و استات سدیم، موجب استخراج انتخابی مس گردید.

چکیده [English]

In this study, solvent extraction of copper from nickel in the presence of tartaric acid and sodium acetate with D2EHPA was studied. To investigate the behavior of carboxylates, parameters such as pH, carboxylate concentration and time were varied. According to the results, with the addition of 0.04 and 0.03 g/L of tartaric acid, and sodium acetate, pH of 5.12, and time of 10 min, 90% and 20% copper and nickel were extracted, respectively. At this condition, the separation factor reached a maximum value of 25.75. Therefore, the mixture of tartaric acid and sodium acetate resulted in the selective extraction of copper.
