摘要

建立了基于氧化锑纳米粒子（AO-NPs）的分散固相萃取（DSPE）火焰原子吸收光谱法（FAAS）测定薰衣草茶基质中痕量铜离子的高灵敏度和准确度的方法。以AO-NPs为吸附剂，在设定温度的条件下，采用微波辅助合成方法制备了AO-NPs。在最佳操作条件下，检测限为0.41 μg L−1。在2.5 ~ 40 μg L−1范围内呈线性关系。根据FAAS和AO-NP-DSPE-FAAS系统的LOD值和校准图方程的斜率计算检测功率/灵敏度的增加，分别为169.4和123.1。采用基质匹配校准策略对薰衣草茶基质的回收率在103% ~ 118.2%范围内，表明该方法对薰衣草茶及类似基质是可行的。

A sensitive analytical method for the determination of copper at trace levels with Sb2O4 nanoparticles based dispersive solid phase extraction

This study presents antimony oxide nanoparticles (AO-NPs)-based dispersive solid phase extraction (DSPE) method for the determination of copper ions in lavender tea matrices with high sensitivity and accuracy at trace levels by flame atomic absorption spectrometry (FAAS) system. AO-NPs used as sorbent material were produced by microwave-assisted synthesis method by setting a defined temperature program. Limit of detection (LOD) value was calculated as 0.41 μg L⁻¹ under optimal operating conditions. Linearity was obtained in the range of 2.5–40 μg L⁻¹. Increase in detection power/sensitivity were calculated based on LOD values of FAAS and AO-NP-DSPE-FAAS systems and the slopes of the calibration plot equations and were found to be 169.4 and 123.1, respectively. The recovery results in lavender tea matrices recorded in the range of 103 %–118.2 % by employing the matrix matching calibration strategy indicated that the presented method is feasible for lavender tea and similar matrices.
