摘要

本研究建立了一种紫外-可见（UV-VIS）吸收光谱法，用于定量检测天然水体中的双氯芬酸钠。对紫外可见吸收光谱法的几个参数进行了优化。根据溶剂的不同，最大吸收波长在 276 至 292 nm 之间，摩尔吸收系数大于 104 L mol-1 cm-1。紫外-可见光谱校准曲线的线性范围在一至三个数量级之间，相关系数 (R2) 非常接近统一。较低的相对标准偏差 (RSD) 值表明测量结果具有良好的重现性。对天然水体的分析应用取得了令人满意的结果，平均回收率在 94.7% 到 99.1% 之间。

Diclofenac analysis in natural waters using UV-visible absorption spectrometric method

In this work, we developed an UV-visible (UV-VIS) absorption spectrometric method for the quantification of sodium diclofenac in natural waters. Several UV-VIS absorption method parameters were optimized. The maximum absorption wavelength was comprised between 276 and 292 nm, depending on the solvent, with molar absorption coefficients greater than 104 L mol-1 cm-1. The linearity of the UV-VIS calibration curves extended over one to three orders of magnitude, with correlation coefficients (R2) very close to unity. The low relative standard deviation (RSD) values indicated a good reproducibility of the measurements. Analytical applications to natural waters yielded satisfactory results with average recovery rates between 94.7 and 99.1%.
