Ion-exchanges of Cu2+, Zn2+, and Ag+ on layered phosphates of tetravalent metal, Zr(HPO4)2·H2O (α-ZrP), Ti(HPO4)2·H2O (α-TiP), Ti(HPO4)2·2H2O (γ-TiP), Ce(HPO4)2·1.33H2O(CeP), Zr(NaPO4) (HPO4) (NaH-ZrP), and Zr(NaPO4)2·H2O (NaNa-ZrP), were studied. Although the uptakes of Cu2+ and Zn2+ into layered phosphates (α-ZrP, TiP, and CeP) were very low, those into NaH-ZrP and NaNaZrP were high. Ag+ was well ion-exchanged by layered phosphates except α-ZrP. Layered phosphates ion-exchanged with metal ions (Cu2+, Zn2+, and Ag+) easily adsorbed ill-smelling gases such as H2S and CH3SH.
