In this work, cross-linked silicone films containing eugenol-based azo dyes (azoeugenol) were obtained as a classical two components formulations. These films were further investigated for their possible application as heavy metal ion binding. With the aid of spectroscopy in the UV–visible spectrum, it was proved that the films effectively bind heavy metal ions by the example of Cu ions being placed both in either aqueous solutions or solutions with organic solvents. In addition, both by spectroscopy and visually, it was revealed that the films change their color after the binding of Cu ions. Based on the collected data, it can be concluded that silicone films containing azoeugenol fragments can be considered as effective sorbents of heavy metals from various media.

具有基于丁子香酚的偶氮染料部分的有机硅薄膜，对 Cu2+ 金属离子有响应

在这项工作中，获得了含有丁子香酚基偶氮染料（azoeugenol）的交联有机硅薄膜，作为经典的双组分配方。进一步研究了这些薄膜作为重金属离子结合的可能应用。借助紫外-可见光谱光谱，通过将铜离子置于水溶液或有机溶剂溶液中的例子，证明了薄膜可以有效地结合重金属离子。此外，通过光谱和视觉，都表明薄膜在结合铜离子后颜色发生变化。根据收集的数据，可以得出结论，含有偶氮丁香酚片段的有机硅薄膜可被认为是各种介质中重金属的有效吸附剂。
