Pesticide elimination through adsorption by metal-organic framework and their modified forms

Simultaneous removal of mixed pesticides and natural organic matter from surface waters by nitric and chlorosulfonic acid functionalized powdered activated carbon

“…17,18 Adsorption is a versatile and efficient process that has gained prominence as a method for mitigating pesticide contamination as a consequence of its high efficiency, ease of application, low cost, and no toxic by-products. [19][20][21] Because the capacity and selectivity of the adsorbents are typically used to evaluate the adsorption performance, the choice of adsorbent is a crucial factor for pesticide adsorption. 21 Furthermore, for the effective removal of pesticides by adsorption, the selectivity and capacity of adsorbent can be enhanced by insertion of various functional groups or active sites onto the adsorbent surface.…”

Structural diversity of three new Co(ii)-based MOFs as a UV light-driven photocatalyst: photocatalytic performance

“…Therefore, pesticide removal is essential for environmental safety as well as public health. [20][21][22][23] MOFs are multidimensional infinite materials that consist of metal clusters linked by polydentate ligands. They have been a School of Chemistry and Environmental Engineering, Sichuan University of Science at the forefront of current material research due to their outstanding uses in the disciplines of adsorption, catalysis/photocatalysis, separation, magnetism, photoluminescence, and drug delivery, as well as their structural aesthetics and excellent porosity.…”

Metal–Organic Frameworks as Potential Agents for Extraction and Delivery of Pesticides and Agrochemicals

“…Among these, adsorption has proved to be superior in terms of cost and efficacy by providing a noncomplex and more efficient method for pesticide extraction . For a competent adsorption, several factors must be considered: the adsorbent must be carefully chosen for its high porosity, surface area, the availability of adsorption sites . In addition, their stability must be considered for agricultural applications to prevent cross-contamination as a result of structural deterioration.…”

“… 44 For a competent adsorption, several factors must be considered: the adsorbent must be carefully chosen for its high porosity, surface area, the availability of adsorption sites. 45 In addition, their stability must be considered for agricultural applications to prevent cross-contamination as a result of structural deterioration. Several adsorbents have been investigated for the adsorption of pesticides from the environment, like activated carbon, 46 zeolites, 47 and clays; however, there are some drawbacks concerning their applications, as a result of their limited resources, low porosity, stern nonfunctionality, and instability.…”
