Abstract

MIL-53/rGO material has been synthesized in a 2-step process on the basis of metal organic framework material of MIL-53(Fe) and reduced graphene (rGO). Material characteristics were studied through XRD, SEM, and electrochemical DPV measurements. Electrochemical sensor based on nanocomposite MIL-53(Fe)/rGO material has been developed, showing outstanding advantages including the ability to detect directly Cd²⁺ ions in aqueous solution, fast detection time and sensitivity. quite tall. The relationship between the sensor output signal (I_peak) and the concentration of Cd²⁺ ions in the range 1 to 9 μM is linear, having the square of the correlation coefficient R² = 0.9705.
