“…The pH of the electrolyte solution will play a vital role in affecting the peak potential and anodic peak current. , The consequence of pH on electrochemical detection PMH was examined using 200 μM concentration at pH ranging from 5.0 to 9.0 at a constant sweep rate of 50 mVs –1 , as displayed in Figure a. The shifting in the peak potential and the increase–decrease in the current response designates the importance of pH on quantification of PMH.…”

In the realm of electrochemical sensor application, the development and fabrication of semiconducting metal oxides with the integration of conducting polymers for the trace-level detection of pharmaceutical medicines garnered considerable interest. Herein, we reported facile cadmium oxide decorated with polypyrrole nanotubes fabricated on a glassy carbon electrode (CdO@PPy/GCE) for efficient determination of antihistamine drug promethazine hydrochloride (PMH). The as-synthesized CdO@PPy composite was characterized by various analytical tools like X-ray powder diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, and X-ray photoelectron spectroscopy. Furthermore, the electrocatalytic activity of the modified electrode for PMH detection was examined by voltammetry and amperometric methods, and the modified electrode exhibited lower charge transfer resistance compared to the bare GCE. Under the optimized condition, the fabricated electrode shows a wide linear range (50−550 μM), better sensitivity (0.13 μAμM −1 cm −2 ), low detection limit (10.83 nM) (S/N = 3), and excellent selectivity and reproducibility toward PMH detection. Moreover, the modified GCE depicted eminent practical ability for PMH detection in lake water and pharmaceutical tablets.

“…As shown in the analysis, the reduction current is directly proportional to the scan rate applied, and the slope value is exactly 0.5 confirming that the electrocatalytic reduction of NFT on CTMs/GCE surface is a diffusion-controlled process. 59,60 Furthermore, the number of electrons that participated in the reduction of NFT is calculated using the Laviron's equation mentioned below eqn (3). 61 where B pc represents the slope of the linear plot of log scan rate (mV s −1 ) vs. log potential ( V ); ‘ n ’ indicates the number of electrons participating in the reduction of NFT; ‘ α ’ is the charge transfer coefficient; ‘ R ’ defines the universal gas constant; ‘ T ’ denotes experimental temperature in K , and ‘ F ’ represents the Faraday constant.…”

“…The synthesized COF TDBA-TTL was similar to sea urchins (4.61 µm diameter), and many well distributed nanowires grew from the surface of the sphere. An appropriate concentration was regarded as a necessary condition for the synthesis of SmV/COF TDBA-TTL [34,35]. Therefore, 0.0100 M, 0.0500 M, 0.100 M, 0.150 M, and 0.200 M SmV were added to the same amount of COF TDBA-TTL to determine the optimal concentration of SmV/COF TDBA-TTL .…”

A Novel Rare Earth and Covalent Organic Framework Composite for Rapid and Highly Sensitive Electrochemical Analysis of Sulfadiazine in Fish Muscle

The misuse of sulfadiazine (SFZ) has led to great hazard to the environment and human safety; therefore, a simple, rapid, and sensitive method to detect sulfadiazine is urgently needed. Herein, we report a simple fabrication method for rare earth vanadate samarium (SmV)-doped covalent organic framework COFTDBA-TTL nanocomposites (SmV/COFTDBA-TTL), which were used to construct a sulfadiazine (SFZ) electrochemical sensor. The synergistic effect arising from the combination of SmV and COFTDBA-TTL accelerates the charge transfer kinetics, along with the creation of more surface-active sites that benefit effective detection. Compared with other electrochemical sensors, this electrochemical sensor exhibits low detection limit (2.40 nM), wide linear range (7.32–12.0 μM), good reproducibility (RSD = 0.823%), and stability (RSD = 3.60%). It provides a novel method and theoretical basis for the application of rare earth COF-based electrochemical sensors to detect environmentally destructive pollutants.
