Abstract
One of the heavy metal ions is copper ion (Cu2+) which is an essential element in many physiological and pathological processes including cell respiration and bone formation. On other hand, Cu2+ at high concentrations can be harmful owning to damage of central nervous system that led to Wilson and Parkinson diseases [1]. The United States Environmental Protection Agency (EPA) regulated Cu2+ concentration in drinking water should not exceed an action level of 20 µM (1.3 ppm) [2]. Therefore, analysis of low concentration of Cu2+ ions by a method with a low cost, rapid response and simple operation is high demand. Until now, various atomic analytical techniques have been utilized for the determination of Cu2+ ions, including graphite furnace atomic absorption spectrometry (GFAAS) [3], flame atomic absorption spectrometry (FAAS) [4], inductively coupled plasma-optical emission spectrometry (ICP-OES) [5], and inductively coupled plasma-mass spectrometry (ICP-MS) [6]. In the present study, a facile and new fluorescent probe based on deep eutectic solvent capped CdSe QDs (DES-CdSe QDs) for the fast sensing of Cu2+ ions was reported. The DES-CdSe QDs were prepared in aqueous phase in one step procedure under ambient atmosphere. The DES-CdSe QDs was extensively characterized using FT-IR, and UV-Vis spectroscopy,transmission electron microscopy and x-ray energy dispersive analysis.
