摘要

:层状双氢氧化物（LDHs）是一类可在实验室环境中轻松合成的材料。这项研究成功合成了一种新型纳米材料（ZnMnAl LDH）。利用傅立叶变换红外光谱（FTIR）、X射线衍射（XRD）、扫描电镜制图（SEM-mapping）和FE-SEM等多种分析技术完成了该材料的表征。ZnMnAl LDH 被用来从土壤和水样中分离和富集铜（II）和镍（II）。用 2 mL 0.1 mol L -1 的 HNO 3 从 ZnMnAl LDH 纳米颗粒中洗脱出 Cu 和 Ni 离子。使用火焰原子吸收光谱（FAAS）对金属离子进行定量。研究考察了许多分析因素对金属离子萃取效率的影响。这些参数包括 pH 值、吸附剂用量、洗脱液用量、洗脱液浓度、样品体积、吸附剂用量和洗脱液浓度。

A New Micro-Solid Phase Extraction Using ZnMnAl LDH Nano-Sorbent For Cu And Ni Determination In Natural Water And Soil

: Layered double hydroxides (LDHs) are a class of materials that may be readily synthesized in a laboratory environment. This work successfully conducted the synthesis of a new nanomaterial (ZnMnAl LDH). The characterization of this material was accomplished utilizing many analytical techniques, including FTIR, XRD, SEM-mapping, and FE-SEM. ZnMnAl LDH was employed to separate and enrich Cu(II) and Ni(II) from soil and water samples. The Cu and Ni ions were eluted from ZnMnAl LDH nanoparticles by using 2 mL of 0.1 mol L −1 of HNO 3 . The metal ions were quantified using flame atomic absorption spectrometry (FAAS). An investigation was conducted to examine the impact of many analytical factors on the efficiency of metal ions' extraction. These parameters include pH, sorbent amount, eluent volume, eluent concentration, sample volume
