Abstract

Iron ions play a crucial role in various biological, environmental, and industrial processes, making their quick and on-site detection in aqueous solutions a significant analytical challenge. This study presents a simultaneous colorimetric detection method for Fe(II) and Fe(III) ions in aqueous solutions using silver nanoparticles (AgNPs) functionalized with chromotropic acid (CTA). The detection of Fe(II) and Fe(III) ions based on CTA-AgNPs was monitored both visually and through ultraviolet–visible spectrophotometry (UV–vis). We discover a variation in nanoparticles size and absorption with their interaction with different ions, which allow us to determine analytical parameters such as the detection and quantification limits. This colorimetric system showed excellent selectivity to the detection of Fe(II) and Fe(III) ions, even in the presence of other metal cations that could potentially interfere the analysis. This approach offers a robust and efficient method for detecting iron ions, with potential applications in environmental monitoring and industrial processes.

变色酸活化银纳米粒子：一种方便的二价和三价铁离子选择性测定的比色传感器

铁离子在各种生物、环境和工业过程中发挥着至关重要的作用，使其在水溶液中的快速和现场检测成为一项重大的分析挑战。本研究提出了一种利用变色酸（CTA）功能化的银纳米粒子（AgNPs）同时比色检测水溶液中铁（II）和铁（III）离子的方法。采用目测和紫外可见分光光度法（UV-vis）监测CTA-AgNPs对Fe（II）和Fe（III）离子的检测。我们发现纳米颗粒的大小和吸收随其与不同离子的相互作用而变化，这使我们能够确定检测和定量限等分析参数。该比色系统对铁（II）和铁（III）离子的检测显示出极好的选择性，即使在其他可能干扰分析的金属阳离子存在的情况下。这种方法为检测铁离子提供了一种强大而有效的方法，在环境监测和工业过程中具有潜在的应用前景。
