Water contamination has turned into one of the most serious issues in the world. Nanomaterials are proficient to carry away heavy metals, organic and inorganic dyes, pesticides, and small molecules from polluted water. In this regard, nanoparticles have gained much attention due to their extraordinary properties compared to bulk materials. Metal oxide nanoparticles and nanocomposites have several advantages such as elevated surface area, low concentration, easily separable after treatment and so on. Among many feasible techniques, the adsorption process is one of the most useful techniques for removing heavy ions and dyes from wastewater and has gained much attention from researchers. Several studies on metal oxide nanoparticles and their use in wastewater treatment have been published in the literature. This chapter gives an outline about five metal oxide based nanomaterials and nanocomposites as well as their applications in water pollution removal where the efficiency, limits and favourable circumstances are compared and explored. This article surely helps to gather information about some metal oxide nanoparticles and nanocomposites in wastewater treatment by the adsorption technique. In this review article, we primarily focused on five metal oxide nanoparticles and some of their recent applications published in the last two years.
水污染已经成为世界上最严重的问题之一。纳米材料能够有效地从受污染的水中去除重金属、有机和无机染料、农药和小分子。在这方面，由于纳米颗粒与块状材料相比具有非凡的性质，因此引起了广泛关注。金属氧化物纳米颗粒和纳米复合材料具有几个优点，例如高表面积、低浓度、处理后易于分离等。在许多可行的技术中，吸附法是去除废水中重金属离子和染料的最有用技术之一，引起了研究人员的广泛关注。已经有许多关于金属氧化物纳米颗粒及其在废水处理中的应用的研究在文献中发表。本章概述了五种基于金属氧化物的纳米材料及其纳米复合材料，以及它们在水污染去除中的应用，比较和探讨了它们的效率、限制和有利条件。本文通过吸附技术，有助于收集一些金属氧化物纳米颗粒和纳米复合材料在废水处理方面的信息。在这篇综述文章中，我们主要关注了五种金属氧化物纳米颗粒及其在过去两年中发表的一些最新应用。
