عنوان انگلیسی Simultaneous Electrochemical Detection of Copper and Chromium in Drinking Water using 3-Pyrazolyl-pyran-2-one Modified Carbon Paste Electrode
چکیده انگلیسی مقاله The contamination of drinking water with heavy metals such as copper (Cu²⁺) and chromium (Cr³⁺) poses significant health and environmental risks, necessitating the development of sensitive and selective detection methods. In this study, a carbon paste electrode (CPE) modified with 3-pyrazolyl-pyran-2-one, a heterocyclic ligand containing nitrogen and oxygen donor atoms, was developed for the simultaneous electrochemical detection of Cu²⁺ and Cr³⁺ ions in drinking water. The interaction between the ligand and metal ions w:as char:acterized by Fourier-transform infrared (FTIR) spectroscopy, providing valuable insights into the surface modifications and coordination mechanisms. Electrochemical performance was evaluated using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and square wave voltammetry (SWV), revealing significant improvements in charge transfer efficiency and electrocatalytic response compared to the unmodified electrode. The sensor demonstrated high sensitivity, low detection limits, and excellent selectivity for Cu²⁺ and Cr³⁺ ions, with recovery rates ranging from 95–106% for Cu²⁺ and 92–105% for Cr³⁺, confirming its accuracy and potential for practical applications in water quality monitoring. These results highlight that surface modification with 3-pyrazolyl-pyran-2-one substantially enhances interfacial electron transfer, providing a promising and reliable platform for the detection of heavy metal ions in aqueous environments.
