摘要:

以MgAl-CO₃^2–水滑石(LDH)焙烧产物(LDO)为重金属离子去除剂, 在单一Cu²⁺、Cr(VI)体系和Cu²⁺/Cr(VI)共存体系中探究了LDO对重金属离子的去除性能, 并结合对金属-LDO复合体的XRD、FT-IR和SEM表征阐明了双金属(Cr(VI)阴离子+Cu²⁺阳离子)在LDO上的去除机理。结果表明, Cr(VI)和Cu²⁺在LDO上的吸附表现为多重相互作用的协同吸附效应。除了Cu²⁺的“Jahn-Teller”效应和氢键协同多体效应外, Cu²⁺-CrO₄^2–-LDO体系还发生静电作用、水合作用、配位作用以及共沉淀和继沉淀作用, 形成了Mg-Al-Cu三元复合体。

Abstract：

Layered double oxide (LDO) as a heavy metal ions removal agent was acquired by calcining Mg-Al containing layered double hydroxide (LDH) and then the performance of the LDO for removal heavy metal ions was assessed in solutions with single Cu²⁺or Cr(VI) and with mixture of Cu²⁺and Cr(VI). The spent adsorbents were characterized by XRD, FT-IR and SEM to clarify the co-adsorption mechanism of Cr(VI) and Cu²⁺ on the LDO. The results show that the co-adsorption of Cu²⁺and Cr(VI) on the LDO can be ascribed to a synergistic effect of multiple interactions: apart from the “Jahn-Teller” effect of Cu²⁺ and many-body terms to hydrogen bonds interaction, there may exist effects such as hydration, electrostatic interaction and coordination etc in the system Cu²⁺-CrO₄^2–-LDO, which enhanced the co-precipitation and subsequent precipitation on the adsorbent surface, therewith, the synergistic effect promoted the formation of Cu²⁺-CrO₄^2–-LDO hybrids.

Key words： inorganic non-metallic materials hydrotalcites heavy metal ions Cu²⁺/Cr(VI) Jahn-Teller effect
