Abstract

Water pollution due to heavy metals has become a universal environmental problem. Ni(II) is a common heavy metal ion in polluted wastewater, which has high toxicity and carcinogenicity. In this study, the structure of a calcium-iron layered double hydroxide (Ca-Fe-LDHs) was synthesized and characterized by FTIR, XRD, SEM and XPS. Then, Ni(II) ion was effectively removed by Ca-Fe-LDHs and its mechanism for this materials was described. The maximum adsorption capacity of Ni(II) for Ca-Fe-LDHs was 418.9 mg‧g when the initial concentration of Ni(II) was 1 g/L. The adsorption and removal of Ni(II) by Ca-Fe-LDHs was attributed to the action of hydroxyl groups on the hydrotalcite, generating surface capture. Ni(OH))0.75(HO)0.16(NiCO)0.09, Ni(OH), NiO, NiSO and other precipitates were generated on its surface. And a small amount of Ni-Fe-LDHs was generated through isomorphic transition before hydrolysis. Therefore, surface capture and isomorphic transition enhanced the removal efficiency of Ni(II) with Ca-Fe-LDHs, making Ca-Fe-LDHs as a potential material for effective removal of Ni(II).

摘要

重金属导致的水污染已成为一个全球性的环境问题。镍（II）是污染废水中常见的重金属离子，具有高毒性和致癌性。在本研究中，合成了钙铁层状双氢氧化物（Ca-Fe-LDHs）的结构，并通过傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、扫描电子显微镜（SEM）和X射线光电子能谱（XPS）对其进行了表征。然后，Ca-Fe-LDHs有效地去除了镍（II）离子，并描述了该材料对镍（II）离子的去除机制。当镍（II）的初始浓度为1 g/L时，Ca-Fe-LDHs对镍（II）的最大吸附容量为418.9 mg‧g。Ca-Fe-LDHs对镍（II）的吸附和去除归因于水滑石上羟基的作用，产生表面捕获。其表面生成了Ni(OH))0.75(HO)0.16(NiCO)0.09、Ni(OH)、NiO、NiSO等沉淀物。并且在水解前通过同晶转变生成了少量的Ni-Fe-LDHs。因此，表面捕获和同晶转变提高了Ca-Fe-LDHs对镍（II）的去除效率，使Ca-Fe-LDHs成为有效去除镍（II）的潜在材料。
