How to Replace a carbonate ion of layered double hydroxide containing carbonate ions and method of manufacturing the anion-exchange layered double hydroxides

摘要

The general formula: Q _a T (OH) _z (CO ₃^2-)_{0.5-b /} 2 (X ^-) (wherein, _b · nH ₂ O 1.8 ≦ a ≦ 4.2.z = ₂ (a + 1) .0 ≦ b 0.5.0 ≦ n ≦ 5.Q metal .X trivalent metal .T divalent ^- carbonate which is represented by atomic group) atoms or the monovalent anion. as a starting material the ion layered double hydroxide, there is provided a method of producing anion exchange LDH that was increased to a maximum 1 less than 0.5 b, (wherein the acidic compound (MX _{m) m} = 1, In the case of 3.m = 1, M is "and · H, R, R and R '" NRR'R H or the case of three or .m = 2 is an organic group or H, and M is a divalent or 2 or contacting an alcohol solution containing a metal salt.) is a trivalent metal.
