چکیده

 استخراج و انتقال توریم (IV) از محلول‌های نیتراتی با استفاده از غشای درون پلی‌مری پلی‌وینیل کلرید / دی (2- اتیل‌هگزیل) فسفریک اسید (D2EHPA/PVC) مورد بررسی قرار گرفت. اثر پارامترهای اصلی سیستم (یعنی، pH فاز دهنده، نوع و غلظت اسید در فاز پذیرنده، درصد D2EHPA در غشا، غلظت اولیه‌ی توریم (IV) در فاز دهنده) بر روی فرایندهای استخراج و انتقال، به روش ناپیوسته بررسی شد. بیش‌ترین مقدار ضریب انتقال توریم با استفاده از غشای تشکیل شده از %45 وزنی D2EHPA و %55 وزنی پی‌وی‌سی، محلول 112 میلی‌گرم بر لیتر توریم با 1.8 pH به عنوان فاز دهنده، محلول 3 مول بر لیتر سولفوریک اسید به عنوان فاز پذیرنده (محلول عریان‌ساز)، برابر با %94.81 به دست آمد.

چکیده [English]

Extraction and transport of thorium (IV) from nitrate solutions was investigated using  polymer inclusion membrane (PIM), based on di(-2-ethylhexyl) phosphoric acid (D2EHPA) and poly(vinyl chloride) (PVC). This study investigates the influence of the main system parameters (i.e., pH of donor phase, type and concentration of acid  in acceptor  phases, percentage of D2EHPA in the membrane, initial Th(IV) concentration) on the extraction and transport process by means of  batch method. The transport factor of Th(IV) as high as 94.81% were recorded using a membrane composed of 45% D2EHPA, and 55% PVC (w/w) from a solution containing 112 mg L-1 Th(IV) in 0.0158 mol L-1 HNO3 (pH 1.8) into a solution containing 3 mol L-1 H2SO4.
