چکیده
برای بررسی امکان کاهش مقادیر مولیبدن موجود در محلول فروشویی اورانیم تا حد استاندارد، آزمایش‌های جذب با استفاده از چند نوع زغال فعال انجام شد. با بهینه‌سازی پارامترهای مؤثر بر جذب مولیبدن توسط زغال فعال، 83.59% مولیبدن موجود در محلول فروشویی با زغال فعال نوع Norit PK 0.25-1 جذب شد. از آن جایی که شرایط مطلوب در آزمایش جذب مولیبدن، کم‌ترین میزان جذب اورانیم می‌باشد، با انجام آزمایش‌های بهینه‌سازی مقدماتی، میزان جذب اورانیم توسط زغال فعال به 2.74%. کاهش یافت.

چکیده [English]
In this work, the possibilities of molybdenum content reduction in uranium leach liquor was investigated by adsorption techniques. Several activated charcoals were used as adsorbents. Under the optimized condition, 83.59% of molybdenum was adsorbed with “Norit PK 0.25-1” activated charcoal. Since the low uranium adsorption is the aim of this work, by performing the optimization conditions, the uranium adsorption with activated charcoal was determined to be 2.74%.
