We report a fast and ultrasensitive colorimetric method for the detection of transition metal ions (Fe, Cu, Ni) in a mixture of toluene-acetonitrile using Schiff base functionalized gold nanoparticles. We achieved limits of detection for the three metal ions at least two orders of magnitude lower than the EU recommended limits. Finally, our methodology was assessed for the determination of nickel in the organic waste of a relevant industrial reaction.
我们报告了一种快速、超灵敏的比色法，用于在甲苯-乙腈混合物中检测过渡金属离子（Fe、Cu、Ni），使用席夫碱功能化的金纳米粒子。我们实现了对三种金属离子的检测限，比欧盟推荐的限制低至少两个数量级。最后，我们的方法学用于测定相关工业反应的有机废物中的镍。
