Layered double hydroxides containing Zn2+ and Al3+ ions with formula [Zn1-xAlx(OH)2]x+[(NO3-)x/2xmH2O] has been prepared using coprecipitation method at pH 10 to form Zn/Al layered double hydroxides (LDH). Zn/Al LDH then intercalated with Keggin ion of [α-PW12O40]3- to form intercalated Zn/Al LDH. Materials were characterized using X-Ray and IR analyses. Zn/Al LDH and intercalated Zn/Al was applied as adsorbent of Cd(II) using batch system. Analysis of X-Ray and IR on Zn/Al LDH and intercalated Zn/Al with [α-PW12O40]3- showed that synthesis of Zn/Al was successfully conducted which was indicated from diffraction at 11 deg and vibration at around 400-500 cm-1 for Zn-O and Al-O vibrations. Analysis of pH PZC on LDH showed that materials have pH PZC at 5. Adsorption of Cd(II) on Zn/Al LDH and intercalated Zn/Al LDH with [α-PW12O40]3- at showed that intercalated Zn/Al LDH with Keggin ion of [α-PW12O40]3- has higher adsorption capacity than Zn/Al LDH without intercalation.
