Separation of Yb as YbSO4 from the Yb target for production of Lu via the Yb(n, gamma)Yb- > Lu process

An effective and simple process for the separation of Lu from neutron-irradiated Yb targets was developed. Irradiated Yb target was dissolved in H2SO4 solution and after reduction with sodium amalgam Yb was precipitated in the form of YbSO4. From 50 mg of Yb irradiated target only 1 mg Yb remains in...

Description
Summary:An effective and simple process for the separation of Lu from neutron-irradiated Yb targets was developed. Irradiated Yb target was dissolved in H2SO4 solution and after reduction with sodium amalgam Yb was precipitated in the form of YbSO4. From 50 mg of Yb irradiated target only 1 mg Yb remains in solution after precipitation and separation of YbSO4. The overall recovery of Lu is estimated at 73%. Further efficient chromatographic separation of carrier-free Lu from 1 mg of Yb is relatively easy and is described in several papers.
