Electrochemical Measurement of Platinum Drug Using Carbon Paste Electrode Modified with Silver Nanoparticles and Modifier

This paper used a carbon paste electrode modified with graphene functionalized with silver nanoparticles and triphenylphosphine to measure the drug Platinol. Raman, Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscope (SEM) techniques were used to study the behaviour of Platinol. The electrochemical behavior of platinum on a carbon paste electrode modified with silver nanoparticles and 4-Hydroxy-2-(Triphenylphosphine) was analyzed. Differential Pulse Voltammetry (DPV) in the concentration range of 1-120 μM was linearized in two ranges of 1-20 μM and 20-120 μM, and the detection limit of 0.88 μM was obtained. The effects of disturbing on different species were studied to determine the selectivity. The platinum measurement method was used with the mentioned electrode in actual samples.
