“…SUPRAS corresponds to water-immiscible solvents consisting of amphiphile aggregates, which are generated via self-assembly of amphiphilic molecules. These solvents are excellent alternative solvents to the conventional solvents for the preconcentration of pesticides residues using microextraction techniques as they provide various interactions such as hydrogen bonding, ionic bonding and hydrophobic interaction [ 36 , 37 , 38 ].…”

Extensive use of organophosphorus pesticides in agriculture leads to adverse effects to the environment and human health. Sample preparation is compulsory to enrich target analytes prior to detection as they often exist at trace levels and this step is critical as it determines the concentration of pollutants present in samples. The selection of a suitable extraction method is of great importance. The analytical performance of the extraction methods is influenced by the selection of sorbents as sorbents play a vital role in the sensitivity and selectivity of an analytical method. To date, numerous sorbent materials have been developed to cater to the needs of selective and sensitive pesticides’ detection. Comprehensive details pertaining to extraction methods, developed sorbents, and analytical performance are provided. This review intended to provide a general overview on different extraction techniques and sorbents that have been developed in the last 10 years for organophosphorus pesticides’ determinations in food and water samples.

“…However, incorrect or excessive use can result in high levels of pesticide residues in food products [ [1] , [2] , [3] , [4] ], which can have negative effects on human health and the environment [ [5] , [6] , [7] , [8] ]. Sometimes, even with proper use, the presence of pesticide residues in food and environmental samples (such as vegetables, fruits, water, and soil samples) is unavoidable [ 9 , 10 ], necessitating additional measures to mitigate contamination. Therefore, it is crucial to control the presence of pesticide residues in food matrices for consumer safety and human health.…”

“…The widespread use of pesticides has greatly increased the production of agricultural products and largely met the demand for food from a continuously growing population 1–3 . However, the problems of wasting resources and environmental pollution caused by the misuse of pesticides are increasingly serious.…”

In our work, a cationic lignin (CL) modified bentonite-alginate nanocomposite gel was prepared and used to enhance the sustained release of alachlor. The underlying gel structure-release property relationships were explored. The results showed that the release of alachlor from nanocomposite gel was dominated by Fickian diffusion and closely related to the adsorption capacity and permeability of the matrix. The adsorption capacity of bentonite for alachlor was remarkably improved due to the modification of CL; Furthermore, the permeability of the matrix was further reduced via the electrostatic interaction between CL and the alginate. The release kinetics demonstrated that the sustained release property of modified bentonite-alginate nanocomposite gels was significantly enhanced. The release time of 50% alachlor from bentonitealginate and modified bentonite-alginate nanocomposite gels was 4.4 and 14.1 times longer than that of the release from pure alginate gel, respectively.
