Simultaneous determination of organophosphorus pesticides residues in vegetable, fruit juice, and milk samples with magnetic dispersive micro solid-phase extraction and chromatographic method; recruitment of simplex lattice mixture design for optimization of novel sorbent composites

Determination of organophosphorus in dairy products by graphitic carbon nitride combined molecularly imprinted microspheres with ultra performance liquid chromatography

“…Milk, yogurt and milk powder were purchased randomly from local markets, which were analyzed by the developed method. The milk and yogurt samples processing methods were carried out according to the previous reports ( Ghorbani et al, 2021 , Pan et al, 2022 ). Briefly, 0.3 g MgSO 4 , 0.1 g CH 3 COONa and 1.5 mL of acetonitrile were added to 5 mL milk to precipitate protein.…”

“…In addition, OPPs can also enter and accumulate in animals and humans through the food chain, indirectly leading to a series of poisonous symptoms ( Fu et al, 2022 ). After entering the body, OPPs can bind to acetylcholinesterase, which can result in a large accumulation of acetylcholine leading to the toxicity and death ( Ghorbani et al, 2021 ).…”

Chemiluminescence sensors based on molecularly imprinted polymers for the determination of organophosphorus in milk

“…These milk samples were analyzed with the MIP-MCL sensor. The sample processing method was carried out according to a previous report (Ghorbani et al, 2021;He et al, 2021). Briefly, 0.1 g of CH 3 COONa, 0.3 g of MgSO 4 , and 1.5 mL of acetonitrile were added to 5 of mL milk to precipitate the protein.…”

“…For example, using magnetic covalent organic framework as adsorbent, a simple and efficient magnetic solid-phase extraction method was established to detect OP in fatty milk (Lin et al, 2020). As extraction material, a metal-organic framework combined with Fe 3 O 4 has been applied for simultaneous determination of 5 OP in vegetables, fruit juice, and milk by GC analysis (Ghorbani et al, 2021).…”

Facile hydrothermal synthesis of N-doped fluorescent carbon dots for selective detection of insecticide parathion

“…6 However, excessive use of organophosphates can lead to environmental pollution, food and water contamination, and pose a threat to human health by inhibiting acetylcholinesterase (AChE), [7][8][9] such as causing tumors, nerve disorders, endocrine disruption, immune system disruption, and even death. [10][11][12] As one of the organophosphates, parathion is widely used to control pests in vegetables, fruits, and owers. [13][14][15] Therefore, it is very important to establish a rapid, easy, low-cost method for parathion detection.…”
