Layered double hydroxide (LDH) Ni/Cr intercalated [α-SiW12O40]4- has been prepared using the coprecipitation method. Materials were characterized by X-ray, FTIR, BET, and pHpzc analyses. Material Ni/Cr-[α-SiW12O40] LDHs exhibited a high surface area 98.986 m2 g-1 from 11.030 m2 g-1 for Ni/Cr LDH where the interlayer space was an increase from 7.99 to 10.87 Å with indicated that high crystallinity. Ni/Cr-[α-SiW12O40] LDHs showed higher adsorption capacity for iron(II) is up to 250 mg g-1. Adsorption of iron(II) on LDHs has an endothermic process and classify as physical adsorption.
