The continuous emergence of food additives and contaminants in edibles, especially confectioneries, demands advanced detection methods to ensure public health safety. Vanillin (VAL) sulfadiazine (SD) are paramount concern due their extensive application various products. While VAL is favored for its flavoring attributes, SD, a common antibiotic, can inadvertently contaminate items. For accurate swift these compounds, we introduced an innovative electrochemical sensor using cobalt oxide nanostructures. Notably, synthesizing nanostructures through green approach glucose starch significant advancement, offering both environmental benefits enhanced material properties. novelty the lies eco-friendly synthesis route superior electrocatalytic performance. Preliminary results indicate promising limit (LOD) VAL= 0.003 µM & SD= 0.0055 broad linear range 0.02–209 emphasizing potential real-world quality monitoring. This work, therefore, provides crucial intersection sustainable effective contaminant detection, heralding new era safety evaluation.

We report magnetically-separable, reusable, green-synthesized Fe3O4/rGO/ZnO, as heterogeneous catalyst for photo-Fenton degradation of organic pollutants in aqueous solution under certain treatments. Fe3O4 nanoparticles was using Moringa oleifera leaf extract, while rGO synthesized utilizing Amaranthus viridis extract. Fe3O4/rGO composited sonication treatment. Afterwards, doped with ZnO various concentration ZnO. X-ray diffraction and selected area electron showed that had spinel cubic hexagonal structure, respectively; another phase appeared Fe2O3 structure. Crystallite size decreased the increased. Morphology image almost spherical, non-uniform, slightly dispersed particle agglomerated condition, attaching to sheets. The Fe3O4, Fe3O4/rGO, Fe3O4/rGO/ZnO is 14.3; 14.1; 10.4 nm, respectively. Fourier-transform infrared spectra metallic functional groups, such Fe-O Zn–O at 562–589 462–478 cm−1 also suggests nanocomposite formation. However, blue-shift absorption band gap widening were observed addition. Raman spectroscopy revealed formation as-synthesized GO rGO. Vibrating sample magnetometer exhibited superparamagnetic properties. Removal efficiency photodegradation methylene blue optimal treatment, reached 100 % within 180 min uptake every 30 min. Photodegradation analyzed Langmuir-Hinshelwood kinetic model, resulting rate constant 24.7 × 10−3 min−1 half-life time 28.1 optimum Reusability photocatalytic activity after 3 cycles only a tiny drop catalytic efficiency. Meanwhile, it possesses high stability potential an environmentally friendly reusable photocatalyst wastewater degradation.
