摘要

采用共沉淀法制备了层状双氢氧化物（LDH）Ni/Cr插层[α-SiW12O40]4-。通过X射线、FTIR、BET和pHpzc分析对材料进行了表征。材料Ni/Cr-[α-SiW12O40]LDHs对Ni/Cr LDH表现出从11.030 m2 g-1到98.986 m2 g-1的高表面积，其中层间空间从7.99Å增加到10.87Å，表明高结晶度。Ni/Cr-[α-SiW12O40]LDHs对铁（II）的吸附量高达250mg·g-1。铁（II）在LDHs上的吸附具有吸热过程，属于物理吸附。

Ni/Cr-[α-SiW12O40] Layered Double Hydroxide as Effective Adsorbent of Iron(II) From Aqueous Solution

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.
