“…Moreover, the peak currents increased, and the peak potentials shifted negatively, indicating that Cu-TCPP showed a high catalytic ability toward the oxidation of HQ and CC. As previously reported, Cu 2+ can be seen as the catalytic activity center [32,33]. In conclusion, the Cu-TCPP nanosheets can be used as sensitization material for the simultaneous…”

It is quite important to develop sensitive, simple, and convenient methods for the simultaneous determination of Hydroquinone (HQ) and Catechol (CC) due to their wide existence, the difficulty of degradation, and the high toxicity. Herein, Cu-TCPP nanosheets were prepared in N,N-dimethylformamide (DMF) through the solvent exfoliation method. The morphology and electrochemical performance of Cu-TCPP were characterized, revealing its stacked sheet structure with abundant pores, a fast electron transfer ability, and a large electrode active area. Using Cu-TCPP nanosheets as the sensitive material to modify the glassy carbon electrodes (Cu-TCPP/GCEs), it was found that they had an obvious enhancement effect on the electrochemical oxidation currents of HQ and CC. The signal enhancement mechanism was explored. The Cu-TCPP nanosheets not only enhanced the accumulation abilities of HQ and CC, but also improved their apparent catalytic rate, displaying high sensitivity for HQ and CC. The values of the detection limit were calculated to be 3.4 and 2.3 nM for HQ and CC. A satisfactory recovery was obtained when this method was used in measuring HQ and CC in the water samples.

“…To validate the electrode process, the plot of the peak current versus square roots of scanning rate was drawn, and the resulting plot was a straight line with satisfactory linearity in the interval from 25 to 500 mV/s as presented in Figure 11 with the correlation coefficient (R 2 ) of 0.9978. These results indicate that the electrode process is diffusion-controlled (28,43).…”

“…The influence of changing the employed scan rate for 100 µM BPA in PBS pH 4.0 was examined by the CV technique at the PGA/PGE as demonstrated in Figure 10. The experiment findings acquired from the PGA/PGE displayed a rise in the peak currents with higher applied scanning rate, and they were proportional to each other based on the Randles-Sevcik equation (43). The finding suggested that there was a shift of the oxidation peak potential towards the less negative side.…”

Bisphenol A (BPA), which is an endocrine-disrupting substance, is often utilized as beverage and food packing material, and it may accumulate in nutrition and water sources, which is why it is important to monitor. In this study, for the determination of bisphenol A, electro-polymerization of glutamic acid (GA) was performed on a pencil graphite electrode (PGE). The performance of the sensor (PGA/PGE) for determining bisphenol A was examined utilizing the cyclic voltammetric (CV) and differential pulse voltammetric (DPV) methods. Electrochemical characterization process of the PGA/PGE was carried out by the electrochemical impedance spectroscopy (EIS) and CV methods. The morphological property of the PGA/PGE was investigated by scanning electron microscopy (SEM). The presence of functional groups in the PGA/PGE composition was characterized by Fourier transform infrared spectroscopy (FTIR). The electrochemical behavior of BPA was observed with the bare PGE and the PGA/PGE. Based on the findings, the response of BPA was considerably raised with PGA/PGE. With the optimized parameters and based on the findings from DPV, the BPA oxidation current was linear in a concentration interval of 1.0 to 100 μM (R=0.9992), and the detection limit was found to be 0.37 μM. Detection of BPA in the plastic bottled drinking water sample using PGA/PGE was performed successfully, and the recoveries were in the range of 89.3 to 104.7%. This strategy can provide several prospects in electrochemically determining BPA in practical applications.
