Rapid sol gel synthesis of BaFe12O19 nanoparticles: An excellent catalytic application in the electrochemical detection of tramadol in the presence of acetaminophen
Abstract The present study reports synthesis of BaFe12O19 nanoparticles by sol gel technique followed by its characterization using Energy dispersive X-ray spectroscopy (EDS), X-Ray diffraction (XRD), field emission scanning electron microscopy (FESEM), vibrating sample magnetometer (VSM) analysis, and Fourier-transform infrared spectroscopy (FTIR). The BaFe12O19 nanoparticles have been applied to construct a modified graphite screen-printed electrode (GSPE). BaFe12O19/GSPE has been applied as a working electrode in the analysis of tramadol and acetaminophen by voltammetric techniques. The BaFe12O19/GSPE showed a good selectiveness for analysis of tramadol in the presence of acetaminophen with the separated peak potentials at ∼ 230 mV, and ∼ 700 mV, respectively. Excellent linear calibration curves, ranging from 0.08 to 500.0 µM for tramadol and from 5.0 to 500.0 µM for acetaminophen, with detection limits of 0.025 and 1.5 µM were obtained.
Abstract A novel voltammetric platform has been developed with nanoparticles of antimony oxide (Sb2O3NPs) and multiwalled carbon nanotubes (MWCNTs). Scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and X-ray diffraction method (XRD) were used for the characterization of the novel composite material (Sb2O3NPs/MWCNTs). The proposed composite material was used for the modification of a glassy carbon electrode (GCE). The proposed modified electrode (Sb2O3NPs/MWCNTs/GCE) was applied ...
Abstract This work presents an analytical study of the determination of catechin, extracted from the Brazilian plants Rhizophora mangle, Arrabidaea brachypoda, and Lippia origanoides, using disposable screen-printed carbon electrodes (C-SPE) coupled to a batch injection analysis (BIA) system. Preliminary cyclic voltammetry experiments in acetate buffer solution (pH 4.5) containing catechin revealed reversible redox processes, with anodic and cathodic peak potentials located at ~0.16 V and ~0.10 ...
Abstract A new simple and fast electrochemical method has been developed, in the current paper, to quantify tramadol hydrochloride in pure solutions and pharmaceuticals, employing the flow injection analysis (FIA) technique. To achieve this, a coated-wire electrode detector has been manufactured using tramadol with phospho molibidic acid in the presence of chlorovinyl benzene. The characteristics of this electrode were studied by assessing the optimal conditions, concentration range, minimal lim...

In the present study, a graphitic carbon nitride/Fe3O4 (g-C3N4/Fe3O4) nanocomposite/carbon paste electrode was used as a highly sensitive sensor for the voltammetric determination of tramadol (Tr) in an aqueous solution. The g-C3N4/Fe3O4 nanocomposite was synthesized by simple calcination of g-C3N4 and ferrite (Fe3O4) magnetic nanoparticles, which was then utilized to fabricate a modified carbon paste electrode (g-C3N4/Fe3O4-CPE). The nanocomposite was thoroughly characterized by various techniq...

Regarding artificial intelligence and wearable soft electronics, increasing attention has been dedicated to hydrogel strain sensors. However, traditional hydrogels are insulating and fragile. To obtain a continuous and repeatable electrical signal output upon external stress or strain in a hydrogel, the combination of good mechanical property, good elasticity and high electrical conductivity is demanded. In order to apply hydrogel in the strain sensing field, in this work, a smart, flexible orga...
Abstract In this research, the magnetic, structural and microwave properties of Ba0.5Sr0.5CuXZrXFe12-2xO19 (BSCZH) (where x = 0–0.8) hexaferrite nanoparticle prepared by the auto-combustion sol-gel method have been investigated. The effect of substituted Cu+2-Zr+4 ions of the barium strontium hexaferrite was characterized by FT-IR, XRD, SEM, VSM and VNA methods. The XRD pattern represents that the materials have a single magnetoplumbite phase, and the crystalline size of the particles varies fro...

Sn–Zn–Co-substituted strontium M-type hexaferrite SrZn x Co x Sn2 x Fe12–4xO19 ( x =0.0, 0.3, 0.5, and 0.7) was synthesized via modified sol–gel auto-combustion method. A microwave device was used to obtain the finest particles and to complete the combustion process. By substitution of tetravalent and divalent cations instead of iron, magnetic and structural properties of M-type hexaferrite were changed. So, the effects of Sn4+, Zn2+, and Co2+ doping on the structure and magnetic characteriza...
