Simple, rapid 77As/76,77Ge separation developed.
No carrier added 77As was separated from neutron irradiated 76Ge using silica gel.
∼74% arsenate eluted with methanol with minimal to no Ge breakthrough.
>80–90% arsenate eluted with 12 M HCl:EtOH (1:1200) without Ge breakthrough.
98% 76Ge recovered by elution with 3 mL of aqueous solution (pH ≥ 7).
