Abstract
Palladium (II)-exchanged hydroxyapatite (PdHAP; for example, PdHAP-B has a Pd/Ca ratio= ca 1/200) was prepared by ion-exchanging with Ca2+ from calcined hydroxyapatite and Pd (NO3) 2 in water at 70° C for 24h. The ion-exchange was revealed by inductively coupled plasma analysis; Pd2+ was almost absent in any filtrate that included over 1.6 equimolar amounts of Ca2+ relative to the amount of Pd2+ consumed. The PdHAP (1mol% Pd) ...
