Dual-mode chemosensor and heavy metal detection method using thereof

摘要

The present invention relates to a composition for detecting heavy metal ions including a novel Schiff base, and the chemical sensor using the Schiff base is convenient because it can determine whether a sample contains heavy metals with the naked eye, and heavy metal ions to be detected Since it is less affected by other metal ions and has a very low limit of detection (LOD) for metal ions, selective and precise detection is possible.
