摘要: Layered double hydroxide (LDH) is an inorganic compound with a layered structure and exhibits anion−exchange properties. Its basic chemical composition [M2+1−xM3+x(OH)2](An– )x/nmH2O, where x the M3+/(M2+ + M3+) molar ratio An– indicates anion valency of n (Ingram Taylor, 1967; Allmann, 1968; 1973). crystal consists positively charged brucite-like octahedral layers containing M3+ at M2+ sites, which are electrically neutralized by interlayer anions, water molecules in hydration shell intercalated anions occupying remaining space. Among various types LDHs composed different compositions M3+, Mg−Al LDH has been used practically as antacid flame retardant (Cavani et al., 1991). CO32− (CO3Mg−Al LDH) can be transformed into oxide calcination 450–800 °C according to following reaction:
