Abstract
The purpose of this work was to separate AC-227, whose content is 18%, from the mineral carnotite found in Gomez Chihuahua mountain range in Mexico. The mineral, before processing, is pre-concentrated and passed, first through anionic exchange resins, later the eluate obtained is passed through cationic resins. The resins utilized were 20-50 MESH QOWEX and 100-200 MESH 50 X 8-20 in some cased 200-400 MESH AG 50W-X8, 1 X 8 in other cases. The eluates from the ionic exchange were electrodeposited on stainless steel polished disc cathode and platinum electrode as anode; under a current ODF 10mA for 2.5 to 5 hours and of 100mA for .5 of an hour. it was possible to identify the AC-227 by means of its descendents, TH-227 and RA-223, through alpha spectroscopy. Due to the radiochemical purity which the electro deposits were obtained the AC-227 was low and was not quantitatively determined. A large majority of the members of the natural radioactive series 3 were identified and even alpha energies reported in the literature with very low percentages of emissions of non-identified were observed. We conclude that a more precise study is needed concerning ionic exchange and electrodeposit to obtain an AC-227 of radiochemical
