Abstract The extent of incorporation of Cu2+for Zn2+ in layered zinc hydroxide acetate to convert it to a hydroxy double salt carried out following titrimetric experiments with KOH solution. The reflections present in the powder X-ray diffraction pattern became broad suggestive of incorporation of copper for zinc. Well defined weight-loss steps, in the thermogravimetric trace of zinc hydroxide acetate, became diffused with the inclusion of copper. The intercalation of various polyols (ethylene glycol, diethylene glycol, and propylene glycol)was performed successfully, exploiting the organophilic character of Zn Cu hydroxide acetate. The interlayer spacing expanded for polyol intercalated samples, as indicated by their powder X-ray diffraction patterns.The FT-IR and Raman spectra of polyol intercalated samples confirmed their presence in the interlayer, and the samples showed enhancement in thermal stability. These samples showed mesoporosity and reasonably high surface area (128.6 m2/g). The role of ethylene glycol intercalated Zn Cu hydroxy double salt as an adsorbent to remove harmful and carcinogenic CR dye molecules from aqueous solutions investigated. The physisorption process was majorly responsible for the effective removal of CR dye, following a pseudo-second-order kinetics.

多元醇嵌入铜取代氢氧化锌醋酸盐及其对刚果红染料的吸附作用评价

摘要 在用 KOH 溶液进行滴定实验后，对层状氢氧化锌醋酸锌中的 Cu2+ 对 Zn2+ 的掺入程度将其转化为羟基复盐。粉末 X 射线衍射图中存在的反射变得广泛暗示铜与锌的结合。明确定义的重量损失步骤，在氢氧化锌醋酸盐的热重跟踪中，随着铜的加入而扩散。各种多元醇（乙二醇、二甘醇和丙二醇）的插层成功地进行，充分利用了醋酸锌铜氢氧化物的亲有机特性。如其粉末 X 射线衍射图所示，插入多元醇的样品的层间距扩​​大。多元醇插层样品的 FT-IR 和拉曼光谱证实了它们存在于夹层中，并且样品表现出热稳定性的增强。这些样品显示出中孔性和相当高的表面积 (128.6 m2/g)。研究了乙二醇嵌入的 Zn Cu 羟基复盐作为吸附剂从水溶液中去除有害和致癌 CR 染料分子的作用。物理吸附过程主要负责有效去除 CR 染料，遵循伪二级动力学。
