“…Because food quality and safety are also determined by proper handling, preparation, and storage, it is critical to fully comprehend the impact of food preservation methods and each step involved in food processing. [ 1,4,9 ] Conventional analytical techniques, including HPLC and GC–MS, are currently well accepted and regarded as standards for food sanitation monitoring; however, these traditional procedures are time‐consuming and labor‐intensive, with tedious sample preparation necessitating highly‐priced instrumentation and specialized staff.

“…Ingesting tainted food or water causes more than 200 diseases, like food poisoning, diarrhea, indigestion, neurotoxicity, and others, even at low doses resulting in about two million deaths per year, according to the World Health Organization (WHO). [ 1–4 ] Residues of dangerous material in food include toxicological elements like metal ions, pesticides, insecticides, veterinary pharmaceuticals, illicit additives, antibiotics, pathogenic microbes, mycotoxins, toxic industrial waste, and so on; as a result, contaminants might arise at any stage during the food preparation process, so convenient and quick detection is mandatory. Many polymer [ 5,6 ] and metal‐based materials [ 7 ] are used as adsorbents for water treatment and the food packaging industry.…”

Food safety and quality are among the most significant and prevalent research areas worldwide. The fabrication of appropriate technical procedures or devices for the recognition of hazardous features in foods is essential to safeguard food materials. In the recent era, developing high‐performance sensors based on carbon nanomaterial for food safety investigation has made noteworthy progress. Hence this review briefly highlights the different detection approaches (colorimetric sensor, fluorescence sensor, surface‐enhanced Raman scattering, surface plasmon resonance, chemiluminescence, and electroluminescence), functional carbon nanomaterials with various dimensions (quantum dots, graphene quantum dots) and detection mechanisms. Further, this review emphasizes the assimilation of carbon nanomaterials with optical sensors to identify multiple contaminants in food products. The insights of carbon‐based nanomaterials optical sensors for pesticides and insecticides, toxic metals, antibiotics, microorganisms, and mycotoxins detection are described in detail. Finally, the opportunities and future perspectives of nanomaterials‐based optical analytical approaches for detecting various food contaminants are discussed.

“…Meanwhile, the quality of irrigation affects the quality of plant growth which can be proven through the presence of azo dyes in plants which have an impact on root damage and inhibit plant growth and photosynthesis because sunlight is blocked by dyes [4]. In terms of human health, azo dye also brings consequences to customer's health due to regular intake of azo-toxic dye-treated foods or by direct contact with it [5]. Therefore, various treatment technology options are needed to set it aside.…”

Azo dyes are widely utilized in a variety of industries, including food, cosmetics, and textiles. Removal of azo dyes from wastewater by the conventional biological process is challenging due to its toxicity. Alternative treatment technology is needed to remove the dye effectively and in a relatively short duration. The processing technology is expected to be able to reduce pollutant materials before they enter water bodies which are a source of agricultural irrigation. In this work, dye removal was studied in some physical and chemical processes, including coagulation (Coag.), Fenton-like oxidation (FLO), and its combination. Synthetic Congo Red (CR) solution was used as a contaminant model of dye wastewater. The assays were performed in a laboratory Jar-Test apparatus with varying FeCl3 coagulant doses (20-30 mg/L), H2O2 doses (42-1,680 mg/L), and coupling mode (Coag.-FLO; FLO-Coag.; FLO/Coag.). The congo red decolorization up to 87% was observed in the coupling of Coag.-FLO process at 24 mg/L FeCl3, 280 mg/L H2O2, pH 8 (Coag.) and pH 3 (FLO). Compared to the removal efficiency of the Coag. (color removal 45%) and FLO (color removal 62%) under selected circumstances. In addition to the higher CR removal, the coupling Coag.-FLO process showed potential cost saving due to less H2O2 dose and partially shift to coagulant.

In the present work, nanoparticles of Al2O3, Cu-Al2O3, and Ni-Al2O3 were prepared using Hibiscus rosa-sinensis plant leaf extract through co-precipitation method. The prepared nanomaterials were characterized through TGA, EDX, SEM, UV-Vis, XRD, and FTIR instruments. The electrochemical behavior of Al2O3, Cu-Al2O3, and Ni-Al2O3 has been studied in DMF solution in the potential ranges from −1.5 to 1.5 V. The nanoparticles are thermally stable, according to the TGA, and the XRD patterns revealed that all the Al2O3, Cu-Al2O3, and Ni-Al2O3 particles were crystalline, with the mean sizes of 12.44, 34.61, and 31.63 nm, respectively. The cyclic voltammogram showed a cathodic peak (Epc) at 0.49 V with an anodic counterpart (Epa) at 0.49 V [E1/2 = 1.748 V]. The optical band gaps of Al2O3, Cu-Al2O3, and Ni-Al2O3 were 3.8, 3.2 and 3.65 eV, owed a cathode. It is observed that the electrochemical behavior of Ni-Al2O3 was identical to that of Al2O3 and Cu-Al2O3. The anodic and cathodic peak values rise with the scan rate. The one-electron oxidation and reduction processes are reversible, as seen by the shifting cathodic peak value toward higher negative values. All cycles exhibit absorption has a constant anodic current. This result indicated the diffusion-based redox process.
