Summary
Due to increasing interest in chemical and fuel synthesis from syngas, the feasibility and practicality of purifying Pt group metals (Pd, Ru, Rh) using LIS technologies have been re-evaluated. Findings for the selective removal of /sup 107/Pd from Pd metal are described here. The selectivity of this technique is based on the angular momentum selection rules for atomic absorption of circularly polarized light. In principle, it is possible to selectively excite isotopes with non-zero nuclear spin, using two circularly polarized laser pulses, while leaving the isotopes with zero nuclear spin unexcited. The excited atom can then be ionized using a third photon of appropriate energy.
