Deep Eutectic Solvent-Assisted Synthesis of a Strontium Tungstate Bifunctional Catalyst: Investigation on the Electrocatalytic Determination and Photocatalytic Degradation of Acetaminophen and Metformin Drugs

“…The correlation coefficient values for ATP R 2 = 0.9916 and R 2 = 0.9913 and MTF R 2 = 0.994 are used to validate these dynamic responses of ATP and MTF. At a signal-to-noise ratio of 3, − this sensing system achieved a low limit of detection (LOD) of ATP = 0.0031 μM and MTF = 0.008 μM, which is considerably lower than the earlier reported modified sensor (Table ). Figure G shows a simplified representation of the electrochemical redox mechanism that the ATP and MTF follow.…”

“…Moreover, the electrochemical active surface area (EASA) of the modified electrodes was tested based on unmodified GCE, SmNbO 4 /GCE, EuNbO 4 /GCE, and NdNbO 4 /GCE as per our previous publications. 31,32 The active surface area was calculated based on the Randles–Sevcik equation (8): I p = 2.69 × 10 5 n 3/2 AD 1/2 υ 1/2 C 0 where I p is the response peak current (μA), C 0 the concentration (mol cm −3 ), n the number of electrons, D the diffusion coefficient (cm 2 s −1 ), υ the scan rate (VMS −1 ), and A the electrochemically active surface area (cm 2 ). Based on the above-mentioned equation, the EASA of the SmNbO 4 /GCE was calculated to be 0.0836 cm 2 , which ensures appreciable electrocatalytic application.…”
