Novel nanosized hydrated zirconium oxide (ZrO(OH)₂) loaded in vermiculite (VMT) was successfully prepared and used to remove Cu²⁺ from aqueous solution. The adsorbent was characterized by XRF, XRD, SEM and TEM. The adsorption process of Cu²⁺ could reach equilibrium within 30 min and its kinetic data could be well described by pseudo-second-order model. The isotherm data could be described better by Langmuir model and the calculated maximum adsorption capacity was 96.23 mg/g. The adsorption of Cu²⁺ on nanosized ZrO(OH)₂ loaded in vermiculite (NZV) was intensively affected by solution pH and different electrolytes. NaClO₄ inhibited the adsorption of Cu²⁺, while NaCl and NaNO₃ promoted the Cu²⁺ adsorption on NZV. The adsorption enhancement by NaNO₃ was much significant than that of NaCl due to more ternary complexes forming among Cu²⁺, NO₃- and the surface of NZV. The adsorption speed and capacity of Cu²⁺ were apparently reduced in the presence of Ni²⁺ in solution, while Cu²⁺ showed a higher affinity to adsorbent than Ni²⁺. The selective adsorption of Cu²⁺ in Cu-Ni mixed solution could be easily achieved in the presence of 0.8 mol/L of NaNO₃, leading to 100% removal of Cu²⁺ and around 5% removal of Ni²⁺.

成功制备了负载在ver石（VMT）中的新型纳米水合氧化锆（ZrO（OH）₂），并用于从水溶液中去除Cu ²⁺。用XRF，XRD，SEM和TEM对吸附剂进行了表征。Cu ²⁺的吸附过程可以在30 min内达到平衡，其动力学数据可以用拟二阶模型很好地描述。等温线数据可以用Langmuir模型更好地描述，计算出的最大吸附容量为96.23 mg / g。溶液pH和不同电解质对Cu ²⁺在负载ver石（NZV）的纳米ZrO（OH）₂上的吸附具有强烈的影响。NaClO ₄抑制Cu ²⁺的吸附，而NaCl和NaNO ₃促进NZV吸附Cu ²⁺。由于在Cu 2 ⁺，NO _3-和NZV表面之间形成更多的三元络合物，因此NaNO ₃的吸附增强作用远大于NaCl 。吸附速度和Cu的容量²⁺中Ni的存在显然降低²⁺在溶液中，而Cu ²⁺显示出对吸附剂除Ni具有更高的亲和力²⁺。在0.8 mol / L的NaNO ₃存在下，很容易实现Cu ²⁺在Cu-Ni混合溶液中的选择性吸附，从而导致100％去除Cu ²⁺Ni ^2+的去除率约为5％。
