“…[ 19,29–33 ] Limited review articles for the analysis of pesticides have been also reported. [ 34–36 ] Because of widespread scientific research related to pesticide analysis, this review aimed to present current information on traditional methods (chromatographic methods, immunoassays, and flow‐injection (FI) systems) along with some novel methods such as paper‐based analytical techniques that are available for determination of pesticides in various food and environmental samples based on CL detection techniques. To the best of our knowledge, there has been no previous review article focusing on CL as a detection technique for pesticide analysis.…”

Chemiluminescence is one of the most coveted methods for sensitive determination of pesticides in food and environmental samples. To date, many methods have been developed for qualitative and quantitative analysis of pesticides, ranging from traditional to advanced methods. This study outlines the progress in the conventional and advanced analytical methods, coupled to a chemiluminescence detection system, that are employed for the determination of pesticides in food and environmental samples. Different analytical methods including chromatographic methods, flow‐based systems, and paper‐based systems are reviewed in this paper. As well, new advances in the application of nanomaterials, aptamer, and molecularly imprinted polymers are highlighted. We also address the challenges and difficulties associated with these methods. Finally, we highlight the future direction in this active field of research.

“…It is widely used in a variety of crops such as fruit trees, tobacco, melons, leafy vegetables, wheat, and cotton to control sucking insects like aphids, moths, beetles, etc. It is soluble in most organic solvents and shows increased solubility in water (i.e., 25 g L −1 ), and this high-water solubility increases its presence in surface water [[ 5 , 6 , 7 , 8 ]]. The systematic name of acetamiprid is (E)-N1-[(6-chloro-3-pyridyl) methyl]-N 2- cyano- N1-methylacetamidine, CAS No: 135410-20-7.…”

Pesticides are one of the main organic pollutants as they are highly toxic and extensively used worldwide. The reclamation of wastewater containing pesticides is of utmost importance. For this purpose, GO-doped metal ferrites (GO-Fe3O4 and GO-CoFe2O4) were prepared and characterized using scanning electron microscopy, X-ray diffraction and Fourier transform infrared spectroscopic techniques. Photocatalytic potentials of catalysts were investigated against acetamiprid’s degradation. A detailed review of the parametric study revealed that efficiency of overall Fenton’s process relies on the combined effects of contributing factors, i.e., pH, initial oxidant concentration, catalyst dose, contact time, and acetamiprid load. ~97 and ~90% degradation of the acetamiprid was achieved by GO-CoFe2O4 and GO-Fe3O4, respectively during the first hour under UV radiations at optimized reaction conditions. At optimized conditions (i.e., pH:3, [H2O2]: 14.5 mM (for Fe3O4, GO-Fe3O4, and GO-CoFe2O4) and 21.75 mM (for CoFe2O4), catalysts: 100 mgL−1, time: 60min) the catalysts exhibited excellent performance, with high degradation rate, magnetic power, easy recovery at the end, and efficient reusability (up to 5 cycles without any considerable loss in catalytic activity). A high magnetic character offers its easy separation from aqueous systems using an external magnet. Moreover, the combined effects of experimental variables were assessed simultaneously and justified using response surface methodology (RSM).

“…These conventional treatment methods have a limitation as carcinogenic nature; formation of byproduct with mutation and non-economical process. Hence, there is need to develop new techniques, the advanced oxidation process is one of the ecofriendly method for the water treatment purpose; it has an ability to degrade water pollutants, heavy chemicals and generating environmental benign by-product (Saleh et al, 2020). Therefore, photocatalyst is the emerging area for the water disinfection as compared to the conventional water disinfection methods (Magalhaes et al, 2017).…”

TiO2 based photocatalyst has potential material for disinfection of harmful pathogens as well as removal of organic compounds. The formation of reactive oxygen species is a key part for overall process but aggregation and band gap constraint explore a new dimension to use of support for propounding its physicochemical properties. Therefore, the modification of TiO2 using various support alters photocatalytic action and promising ways of the mechanism based on nature of substrates and environments. In addition, the immobilization of nano dimension photocatalyst may reduce overall cost of operation and recovery of photocatalytic materials. In this perspective, extensive range of support materials as carbonaceous matters, clay, polymers, metal oxides have been studied by various researchers; that have been compiled in this review article. The properties of support were the key features for the assortment of appropriate supports for increase its efficiency as photocatalyst. In brief, overall TiO2 based photocatalyst supported on various substrates pave the ways toward new strategies for water disinfection.
