بناء حساسات كيميائية كهربائية تعتمد على مركبات الإطار العضوي المعدني القائم على الزركونيوم وكشفها عن الكادميوم

Key Points

• The aim is to develop a high-performance electrochemical sensor for the detection of Cd2+ in water.
• Modified a glassy carbon electrode with NH2-UiO-66 and carbon black composites.
• Optimized key parameters using differential pulse voltammetry.
• Evaluated sensor performance through quantitative analysis in real water samples.
• Achieved a linear detection range of 0.1–10 μM with R2 = 0.9998.
• Sensitivity measured at 9.475 μA/μM and a detection limit of 0.02 μM.
• Demonstrated recovery rates of 93.34% to 103.8% in real water samples.
