Abstract

The presence of organophosphorus contaminants (OPCs) in water is a major concern due to their toxicity and adverse effects on human health and the environment. Traditional water treatment methods such as coagulation, sedimentation, and filtration are not always effective in removing OPCs from water, making it necessary to explore alternative methods. Nanomaterials, due to their unique physical, chemical and biological properties, have emerged as promising adsorbents for the removal of OPCs from water. This review article focusses on the recent developments in the use of nanomaterials as adsorbents for the removal of OPCs from water. The article covers various types of nanomaterials, including carbon-based nanomaterials, metal-based nanomaterials and other hybrid nanomaterials. The mechanisms of OPC adsorption by nanomaterials, such as electrostatic interactions, hydrogen bonding, and Van der Waals forces, are also discussed. The article further highlights the factors affecting the adsorption capacity of nanomaterials, such as pH, temperature, and concentration of OPCs. Additionally, the article examines the challenges associated with the application of nanomaterials in water treatment, such as the potential release of nanomaterials into the environment and the need for cost-effective and scalable synthesis methods.

基于纳米材料的吸附剂在去除水中有机磷污染物方面的最新进展：概述

由于有机磷污染物（OPCs）的毒性及其对人类健康和环境的不利影响，水中存在有机磷污染物已成为人们关注的主要问题。传统的水处理方法，如混凝、沉淀和过滤，并不总能有效去除水中的 OPC，因此有必要探索替代方法。纳米材料因其独特的物理、化学和生物特性，已成为去除水中 OPCs 的理想吸附剂。这篇综述文章重点介绍了使用纳米材料作为吸附剂去除水中 OPC 的最新进展。文章涉及各种类型的纳米材料，包括碳基纳米材料、金属基纳米材料和其他混合纳米材料。文章还讨论了纳米材料吸附 OPC 的机理，如静电相互作用、氢键和范德华力。文章进一步强调了影响纳米材料吸附能力的因素，如 pH 值、温度和 OPC 的浓度。此外，文章还探讨了与纳米材料在水处理中的应用相关的挑战，如纳米材料可能释放到环境中，以及需要具有成本效益和可扩展的合成方法。

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
