三维花状层状双金属氢氧化物的制备及其对甲基橙的去除
|
摘要
以阴离子表面活性剂十二烷基硫酸钠(SDS)为模板剂,制备三维花状LDH(3D-LDH).借助X射线衍射仪(XRD)、傅立叶变换红外光谱仪(FT-IR)等表征手段确定最佳合成SDS浓度,并将最佳条件下产物进行热重-差热分析(TG-DTA)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)分析.此外,将3D-LDH作为吸附剂,研究其对50 mg·L~(-1)甲基橙(MO)的去除性能及机制.结果表明,当SDS浓度高于0.05 mol·L~(-1)时,可形成直径约为1.5—2μm的花状微球.3D-LDH对MO的吸附容量为44.4 mg·g~(-1),吸附动力学符合准二级动力学方程.结合XPS分析,3D-LDH对MO的去除机制主要为离子交换作用.
Three-dimensional flower-like LDH(3 D-LDH) microspheres were successfully synthesized using Sodium dodecyl sulfate(SDS) as the template. The optimal SDS concentration was determined by XRD and FT-IR. Under the optimal condition, the products were characterized by TG-DTA, SEM and TEM. The removal performance and sorption mechanism of Methyl orange(MO) by as-prepared 3 D-LDH were investigated subsequently. The results showed that the flower-like microspheres with the diameters of 1.5—2 μm were formed when the SDS concentration was higher than 0.05 mol·L~(-1). The maximum adsorption capacity of MO by 3 D-LDH was 44.4 mg·g~(-1), and the adsorption kinetics fit the pseudo second-order kinetic equation. The removal mechanism of MO by 3 D-LDH is ion exchange according to the XPS spectra.
