The adsorption characteristics of the adsorbents from allophane have been investigated by means of the comparison of the adsorption quantity of divalent metal ions (Mg, Ca, Sr, Ba, Mn, Co, Ni, Cu, Zn, Cd, Pb). The adsorbents are zeolites (P, type, F type and hydroxy sodalite) synthesized from the volcanic ash in southern Kyushu and amorphous parts (P_1 (Cell) and F(Gell)) which coexist PI type and F type. Adsorption quantities of these metal ions are influenced mainly by the degree of the hydration of the metal ion and the difference between the adsorption quantities of these metal ions on P! type is larger than that on F type. The adsorption quantity of Pb(II) on hydroxy sodalite is large(5.0 meq/g) but those of another metal ions are constant and small(about 1 meq/g). Amorphous parts(P_1(Gell) and F(Gell)) are also able to adsorp the metal ion, but their adsorption quantities are smaller than those on P_1 type or F type. The adsorption characteristic of F(Gell) differs from that of P_1(Gell), but resembles that of F type.
