Abstract
The lead removal ability of two kinds of board-shape hydroxyapatites with different Ca/P molar ratio were evaluated. The samples reacted with Pb(NO3)2 in an aqueous solution produced a mixture of hydroxyapatite and hydroxypyromorphite. The results showed that Board-shape Ca-deficient type HAP(HAP-400) has Pb2+ removal ability superior to Board-shape HAP with stoichiometric composition(HAP-300).
