Abstract

The adsorption of phosphine, cadmium and antimony on copper-palladium alloy films at
288oC was studied by scanning electron microscopy with energy-dispersive X-ray methods (SEM-EDX) characterization. The composition spread alloy film (CSAF) coupons were exposed to cadmium, phosphine or antimony in nitrogen in a small flow reactor. Trends for cadmium, phosphorus and antimony uptake as a function of alloy composition are being determined. The results have potential consequences for the design of sorbents for the capture of phosphorus from fluid streams, and for the stability of palladium-copper alloy membranes employed for hydrogen separation from coal-derived syngas.
