Abstract
⺠Apatites are effective sorbents to remove Cd2+ and Zn2+ in multi-component solution. ⺠Competitive metal sorption reduces the individual amounts of metal ions removed. ⺠The complexation of metal ions with EDTA inhibits their sorption on apatites. ⺠XPS proofs the formation of Ca2+ and Zn2+-substituted surface layer by ion exchange. ⺠Composition of new surface layer on apatite is Ca8.4âxMex(HPO4)1.6(PO4)4.4(OH)0.4.
