“…Among the electrochemical methods is cyclic voltammetry (CV), which offers great versatility to study electroactive substances. Currently, a wide variety of nanomaterials have been designed for the modification of electroactive surfaces, and to optimize the determination of electroactive compounds of interest by increasing their surface and adsorption sites, improving the selective interactions between the electrode and the substance, and achieving a greater sensitivity and performance [12][13][14][15][16][17].…”

This work devised a simple glycerol-assisted synthesis of a low-Cu2+-doped CoFe2O4 and the electrochemical detection of acetaminophen (AC). During the synthesis, several polyalcohols were tested, indicating the efficiency of glycerin as a cosolvent, aiding in the creation of electrode-modifier nanomaterials. A duration of standing time (eight hours) before calcination produces a decrease in the secondary phase of hematite. The synthesized material was used as an electrode material in the detection of AC. In acidic conditions (pH 2.5), the limit of detection (LOD) was 99.4 nM, while the limit of quantification (LOQ) was found to be (331 nM). The relative standard deviation (RSD), 3.31%, was computed. The enhanced electrocatalytic activity of a low-Cu2+-doped CoFe2O4-modified electrode Cu0.13Co0.87Fe2O4/GCE corresponds extremely well with its resistance Rct, which was determined using the electrochemical impedance spectroscopy (EIS) technique and defined its electron transfer capacity. The possibility of a low-Cu2+-doped CoFe2O4 for the electrochemical sensing of AC in human urine samples was studied. The recovery rates ranging from 96.5 to 101.0% were obtained. These findings suggested that the Cu0.13Co0.87Fe2O4/GCE sensor has outstanding practicability and could be utilized to detect AC content in real complex biological samples.

In the present study, we report the green synthesis of novel magnetically separable MgFe 2 O 4 nanoparticles using Cajanus cajan (L.) Millsp leafs via combustion method. The MgFe 2 O 4 were characterized by powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), and UV-Vis spectroscopy. The crystalline structure of MgFe 2 O 4 NPs was con rmed via XRD electron micrograph and TEM showed that the MgFe 2 O 4 NPs were nearly spherical particles with particle size ranging between 5-15 nm. UV-vis DRS study showed the optical band gap of MgFe 2 O 4 NPs was found to be 1.0 eV. Microwaves (MW) assisted degradation of PCM-dolo drug on MgFe 2 O 4 were performed at different operating parameters such as time (0-30 min), drug concentration (PCM-dolo 50 mg/L), initial concentration of MgFe 2 O 4 (0 mg/L -110 mg/L), and microwave power (100W-600W) to obtained the residual absorbance of PCM-dolo on MgFe 2 O 4 . Experimental data was used to compute the degradation e ciency of PCM-dolo on MgFe 2 O 4 . The enhanced catalytic performance could be ascribed to the production of MW-induced active species, such as holes (h + ), superoxide radicals (•O 2 −) and hydroxyl radicals (•OH) in the degradation process. A possible degradation mechanism and pathway was proposed in MW/MgFe 2 O 4 system. Moreover, MgFe 2 O 4 as an eco-friendly catalyst could be easily separated and recycled by a magnet.
