The ultrasound technique was applied to the synthesis of layered double hydroxides (LDH; Mg_xAl_y(OH)_<2(x+y)>CO_3^<2->_<y/2>mH_2O). The effect of the ultrasound on the synthesis of the compounds was studied in terms of crystal quality, metal composition (M^<2+>/M^<3+>) and surface property of the synthesized compounds. The crystal qualities of the compounds synthesized with ultrasound were compared with those of compounds synthesized without ultrasound to elucidate the effect of the ultrasound on the synthesis. The effect of the crystal quality on the water treatment performance was also examined from a viewpoint of removal of organic compound from water using humic substances as adsorbate. The compounds synthesized under ultrasonic conditions showed high crystal quality within a few minutes of treatment and large adsorption capacity for humic substances. The molar ratio of metal cations (M^<2+>/M^<3+>) and specific surface area were increased with increase in the treatment. The amount of the adsorption was well correlated with the crystal quality of the compounds. Ultrasound was found effective in the synthesis of highly crystallized layered double hydroxide with a few minutes of application. It enables the synthesis of the compound simply and rapidly under atmospheric conditions. The crystallite size of the compound increases with increasing the application time and power of ultrasound. The adsorption capacity of the compound for humic substances increases with increasing crystal quality of the compounds.
