穆斯堡尔效应在许多方面得到广泛应用后,
57
Co的生产引起了人们的重视。本文报导了从回旋加速器上照过的铁靶中分离出
57
Co的实验结果。
This paper describes a procedure for the separation of
57
Co for Mössbauer source. The
57
Co was obtained by

Fe (d

Co reaction. The irradiated iron target is etched with 9N HC1 until essentially all the activity is transfered into solution 15% H

is added to oxidize iron to ferric state. The solution is evaporated nearly to dryness. The resulting Fe (III) is dissolved in 4N HC1. Iron is extracted with Tributyl phosphate. The hydrochloric solution again evaporated nearly to dryness then it is dissolved in 9N HC1 and passed through a 717 ion exchanger column. 4N HC1 solution is choosed as eluant for
57
Co. The recovery of
57
Co is over 95%.
