Numerous activities, including rapid industrialization, population increase, and agricultural practices, have continuously contaminated freshwater resources. One of the main risks to aquatic life and human health is water pollution, which can lead to a number of extremely dangerous illnesses, including cancer, asthma, and gastrointestinal problems. The contaminated wastewater could be cleaned using a variety of traditional and cutting-edge techniques. In order to solve these problems, scientists have been investigating a number of treatment techniques, such as adsorption, which uses adsorbents to effectively and selectively remove particular pollutants. Adsorption is the most widely used economical and effective method for treating wastewater and eliminating dangerous contaminants. The surface characteristics of the adsorbents utilized, such as their surface area and availability of functional groups, are what primarily determine the efficacy of adsorption. Since different carbon derivatives derived from waste are used as adsorbents to remove harmful pollutants, nanomaterials have been used as effective adsorbents in recent times because of their superior surface qualities. Particularly magnetite (FeO), magnetic adsorbents have shown great promise as an adsorbent material for water filtration. It is appropriate for the adsorption of numerous pollutants due to its large surface area, supermagnetism, and simplicity of functionalization. In order to eliminate harmful contaminants including heavy metals, dyes, pesticides, and polycyclic aromatic hydrocarbons from wastewater, this review paper critically examined the synthesis of nanomaterials, with a focus on green synthesis. It is anticipated that this kind of multidisciplinary research would lead to more advancements in advanced nanotechnology and nanoscience in the water treatment industry.
包括快速工业化、人口增长和农业活动在内的众多活动持续污染着淡水资源。水污染是对水生生物和人类健康的主要风险之一，它可能导致多种极其危险的疾病，包括癌症、哮喘和胃肠道问题。可以使用各种传统和前沿技术来净化受污染的废水。为了解决这些问题，科学家们一直在研究多种处理技术，例如吸附法，该方法使用吸附剂有效且有选择性地去除特定污染物。吸附是处理废水和消除危险污染物最广泛使用的经济有效方法。所使用吸附剂的表面特性，如表面积和官能团的可用性，是决定吸附效果的主要因素。由于源自废物的不同碳衍生物被用作吸附剂来去除有害污染物，近年来纳米材料因其优异的表面性质而被用作有效的吸附剂。特别是磁铁矿（FeO），磁性吸附剂作为一种用于水过滤的吸附材料已显示出巨大的潜力。由于其大表面积、超磁性和功能化的简便性，它适用于吸附多种污染物。为了从废水中去除包括重金属、染料、农药和多环芳烃在内的有害污染物，本文批判性地审视了纳米材料的合成，重点是绿色合成。预计这种多学科研究将在水处理行业的先进纳米技术和纳米科学方面带来更多进展。
