Abstract

We have synthesized novel sulfonamide-based nano-composite (SAN) for selective and sensitive detection of Fe³⁺ ions in aqueous samples. Morphological characterization of SAN was carried out with TGA, FT-IR, UV-Vis, ninhydrin assay, FE-SEM, pXRD, BET, EDX, and elemental analysis. The sensing nature, effect of pH, sensor concentration and response time analysis were accomplished with the help of emission spectral studies and SAN was assessed as "turn-on" emission detector for the biologically important Fe³⁺ ions. Here, the LOD and LOQ were computed to be 26.68 nM and 88.93 nM, respectively, and it was found to be much lower than the permissible limit of Fe³⁺ ions in drinking water. The accuracy of the sensor (SAN) was determined by testing the aqueous samples spiked with known concentrations of Fe³⁺ ions and results demonstrated 98.00-99.66% recovery, which made SAN a reliable, selective and sensitive chemosensor for the quantification of Fe³⁺ ions in fully aqueous media.

磺胺功能化二氧化硅纳米复合材料:表征和荧光“开启”检测在水样品中的Fe3+离子。

我们合成了一种新的磺胺基纳米复合材料(SAN)，用于选择性和灵敏地检测水样品中的Fe3+离子。通过TGA、FT-IR、UV-Vis、ninhydrin、FE-SEM、pXRD、BET、EDX和元素分析对SAN进行了形态表征。在发射光谱研究的帮助下，完成了传感性质、pH、传感器浓度和响应时间的分析，并评估了SAN是生物学上重要的Fe3+离子的“开启”发射探测器。在这里，计算出LOD和LOQ分别为26.68 nM和88.93 nM，远远低于饮用水中Fe3+离子的允许限值。通过对已知Fe3+浓度的水样品进行测试，确定了传感器(SAN)的准确性，结果显示回收率为98.00-99.66%，这使SAN成为全水介质中Fe3+定量的可靠、选择性和灵敏度高的化学传感器。
