چکیده
در این کار پژوهشی، کادمیوم پرتودیده، طی واکنش هسته‌ای In111 natCd (p,xn) در اسید نیتریک 3 مـولار حل و از ستـون محـتوی 4 گـرم مبـادلـه کننـدة کـاتیـونـی AG 50W-X8 عبور داده شـد. سپس In111 در دو مـرحلـة سـاده، از ناخالصی‌هـای مس وکادمیوم جـدا شد. در مرحلة اول، کادمیوم به وسیله محلول استون-آب- اسید برمیدریک و در مرحله دوم ایندیوم با محلول استون-آب- اسید کلریدریک از ستون خارج می‌شود. محلول خروجی حاوی ایندیوم تا مرحله خشک حرارت داده شد سپس باقیمانده در اسید کلریدریک 0.01 مولار حل شد. بازدهی روش در محلول In111 برابر 1±95 درصد و غلظت ناخالصی‌های مس وکادمیوم آن بترتیب معادل 0.1 و 0.3 میلی‌گرم در لیتر بوده است.

چکیده [English]
In this work, during the nuclear reaction of natCd (p, xn)111In, the irradiated cadmium target was dissolved in 3 M nitric acid. It was passed through a cation exchange column, containing 4 g. of AG 50W-X8,and then was separated from cadmium and copper impurities by using a simple two stage procedure. At the first stage, cadmium was eluted with acetone-water-hydrobromic acid solution. At the second stage, indium was eluted with acetone-water-hydrochloric acid solution. The effluent was evaporated to dry and the residue was dissolved in 0.01M hydrochloric acid. The overall yield of the procedure was 95 ± 1 percent and the amount of cadmium and copper contamination were 0.3 and 0.1 ppm, respectively.
