Abstract

The paper describes a simple, sensitive, and selective spectroscopy method for the determination of Fe by curcumin reagent and iron(III). In acid media, a 1:2 complex was formed; its properties were identified by UV-VIS, FTIR, Raman, and MS spectra. The maximum absorbance of UV-Vis spectra appeared at 518 nm. The parameters of the method for the determination of Fe was validated. Beer’s law was obeyed in the range 0.2×10 M to 2.0×10mol/L of Fe. The limited of detection (LOD) and limited of quantitation (LOQ) has been to be 0.5.0×10 6 and 1.5×10 mol/L. This method was applied to determine the concentration of ferrous total in various samples.

基于姜黄素试剂的光谱定量测定铁(iii)的新方法

本文建立了姜黄素试剂和铁(III)分光光度法测定铁的简便、灵敏、选择性好。在酸性介质中，形成1:2的络合物;通过紫外可见光谱、红外光谱、拉曼光谱和质谱对其性质进行了鉴定。紫外可见光谱的最大吸光度出现在518 nm处。对该方法测定铁的参数进行了验证。铁的浓度在0.2×10 M ~ 2.0×10mol/L范围内符合Beer定律。检测限(LOD)和定量限(LOQ)分别为0.5.0×10 6和1.5×10 mol/L。该方法可用于测定各种样品中总铁的浓度。
