Abstract
The present invention relates to use of an aluminosilicate particle for deodorization, wherein the aluminosilicate particle has the composition of: s M(1)xOy t M(2)2O.Al2O3 u SiO2 v RmQn w H2O, wherein M(1) is one or more members selected from the group consisting of Ag, Cu, Zn and Fe, M(2) is one or more members selected from the group consisting of Na, K and H, R is one or more members selected from the group consisting of Na, K, Ca and Mg, Q is one or more members selected from the group consisting of CO3, SO4, NO3, and Cl, s satisfies 0<s≦3, and t satisfies 0≦t≦3, with proviso that s+t is from 0.5 to 3, and u satisfies 0.5≦u≦6, v satisfies 0<v≦2, w satisfies w≧0, x satisfies 1≦x≦2, y satisfies 1≦y≦3, m satisfies 1≦m≦2, and n satisfies 1≦n≦3, and wherein the aluminosilicate particle has a specific surface area of 1 m2/g or more and less than 70 m2/g.
