Pesticides have been widely used in agriculture to control, reduce, and kill insects. Humans are also being using pesticides to control insidious animals in daily life. By these practices, a huge volume of pesticides is introduced to the environment. Despite broad-spectrum applicability, pesticides also have hazardous effects on both humans and animals at high and low concentrations. Long-term exposure to pesticides can cause different diseases, like leukemia, lymphoma, and cancers of the brain, breasts, prostate, testis, and ovaries. Reproductive disorders from pesticides include birth defects, stillbirth, spontaneous abortion, sterility, and infertility. Therefore, the application of determination and treatment methods for pre-concentration and removal of these toxic materials from the environment appears a vital concern. To date, different materials and approaches have been employed for these purposes. Among these approaches, multifunctional metal-organic frameworks (MOFs)-assisted adsorption and determination processes have always been in the spotlight. These facts are due to exclusive properties of MOFs in terms of the crystallinity, large surface area, high chemical, and physical stability, and controllable structure as well as unique features of adsorption and determination process in terms of simple, easy, cheap, available method and ability to use in large and industrial scales. In the present work, we illustrate the exceptional features of MOFs as well as the possible mechanism for the adsorption of pesticides by MOFs. The use of these fantastic materials for pre-concentration and removal of pesticides are extensively explored. In addition, the performance of MOFs was compared with other adsorbents. Finally, the new frontiers and prospects of MOFs for the determination, sensing, and removal of pesticides are presented.
农药在农业中被广泛用于控制、减少和杀死昆虫。人类也在日常生活中使用农药来控制阴险的动物。通过这些做法，大量的农药被引入环境中。尽管具有广谱适用性，但农药在高浓度和低浓度下对人类和动物都有危险的影响。长期接触农药会导致不同的疾病，如白血病、淋巴瘤和脑癌、乳腺癌、前列腺癌、睾丸癌和卵巢癌。农药引起的生殖障碍包括出生缺陷、死胎、自然流产、不育和不孕。因此，应用确定和处理方法从环境中预先浓缩和去除这些有毒物质显得至关重要。迄今为止，已经采用了不同的材料和方法来实现这些目的。在这些方法中，多功能金属-有机骨架（MOFs）辅助吸附和测定过程一直备受关注。这些事实归因于 MOFs 在结晶度、大表面积、高化学和物理稳定性以及可控制的结构方面的独特性质，以及吸附和测定过程在简单、容易、便宜、可用方法和能够在大规模和工业规模上使用方面的独特性质。在本工作中，我们说明了 MOFs 的特殊性质以及 MOFs 吸附农药的可能机制。广泛探索了这些神奇材料在预浓缩和去除农药方面的应用。此外，还比较了 MOFs 与其他吸附剂的性能。最后，提出了 MOFs 在农药的测定、传感和去除方面的新前沿和前景。
