چکیده
ایتریم- 90 به عنوان یک بتاگسیل با انرژی بیشینهی 2.3MeV و به واسطهی عمر طولانی مادر- هستهاش (استرانسیم- 90)، یکی از مهمترین رادیونوکلیدهای مورد استفاده در پزشکی هستهای است. استفاده از ایتریم به عنوان یک رادیودارو، مستلزم به کارگیری یک روش سریع و انتخابی برای جداسازی آن از مادر- هستهاش است. در این مقاله، رفتار جذبی یونهای ایتریم (III) و استرانسیم (II) بر روی رزین XAD-4 آغشته به بیس (2-اتیل هگزیل) فسفات (HDEHP) در دو حالت پیوسته و ناپیوسته مورد بررسی قرار گرفته است. اثر زمان استخراج در محیطهای مختلف، و اثر غلظت نیتریک و هیدروکلریک اسید بر میزان جذب و واجذب این یونها بررسی شد. مدلهای مختلف سینتیکی نیز به منظور تعیین سازوکار جذب ایتریم مورد بررسی قرار گرفت. برای جداسازی ایتریم از استرانسیم در محیط نیتریک اسید M0.05، محلول شامل 5 میلیگرم برلیتر ایتریم و 1000میلیگرم بر لیتر استرانسیم با آهنگ ml/min1 از ستون کروماتوگرافی عبور داده شد. تحت این شرایط در حالی که ایتریم بر روی رزین نگه داشته شده بود، استرانسیم از ستون خارج و نسبت Y/Sr در محصول شویش برابر 200 محاسبه شد. از نتایج حاصل میتوان در جداسازی ایتریم- 90 از استرانسیم- 90 استفاده کرد.

چکیده [English]
Yttrium-90 as a β emitting with the maximum energy of 2.3MeV, and due to the long half-life of its parent-strontium-90, is considered as one of the most important radionuclides in nuclear medicine. In this context, a highly selective and rapid method for the separation of 90Y from its parent is required for its use in nuclear medicine. In this study, adsorption behavior of yttrium (III) and strontium (II) ions were studied on the Amberlite XAD-4 resin impregnated with (2-ethylhexyl) phosphate (HDEHP) by batch and continuous methods. The effects of extraction time in different media, nitric acid and hydrochloric acid concentrations on the sorption and desorption of ions were investigated. Different kinetic models were examined to determine the adsorption mechanism of yttrium. For the separation of yttrium from strontium in 0.05M nitric acid media, a solution containing 5ppm yttrium and 1000ppm strontium was passed with a flow rate of 1ml/min through a chromatography column. In this condition, while yttrium was retained by the resin, strontium passed through the column. A ratio of 200 was calculated for Y/Sr in eluate. The results of the present experiment can be used for separation of yttrium-90 from strontium-90.
