The document describes a novel method for producing Cr-51 using two different ion exchange separation techniques. The first technique uses triton X-100 cerium(IV)phosphate (TX-100CeP) as an inorganic cation exchanger, while the second uses permutit as an organic cation exchanger. Both techniques separate Cr-51(III) from Cr(VI) using hydrochloric acid as an eluting agent. The TX-100CeP method yielded 90±0.5% Cr-51, while the permutit method yielded 85±0.5% Cr-51. The TX-100CeP method is considered more suitable as it provides high yield with a simple procedure.

[en] The ion exchange separation of 51Cr(III) from Cr(VI)was investigated using two chemical procedures; inorganic cation exchanger
triton X-100 cerium(IV)phosphate (TX-100CeP) and organic cation exchanger permutit. Some factors affecting the separation such as
equilibrium time, HCl concentration, ion exchange capacity, acetone ratio were investigated and the optimum conditions for each were
deduced. The yield of Cr-51 obtained using the TX-100CeP ion exchanger and HCl with acetone solution as eluting agent was 90± 0.5%.
In permutit separation process using HCl as eluting agent, the yield of Cr-51 was 85±0.5%. A comparison of both separation methods of
Cr-51 with the commonly used method was given. The production of Cr-51 by TX-100CeP method appeared to be more suitable, as
providing a simple procedure and a good separation yield
