Removal of cadmium ion by means of synthetic hydroxyapatite

Waste Manag. 2002;22(8):853-7. doi: 10.1016/s0956-053x(02)00078-8.

Abstract

The reaction behaviour of synthetic hydroxyapatite [Ca10(PO4)6(OH)2] (HAP) toward cadmium ion was investigated for the Cd/Ca molar ratio in the range 1-0.005, by means of ions, pH measurements and XRD, SEM, IR techniques. The reaction behaviour between HAP and cadmium ion could be explained by a formation of an amorphous phase and/or a sorption mechanism.
