Heavy metal ion-containing pollution has drawn a lot of attention. It presents thoughtful risks to the human situation and environmental system. Nanotechnologies can control, create, and measure objects on a molecular and atomic size between 1 and 100 nm. Their surface area to volume ratio is high. These are the most practical and are to blame for the easy accessibility, particularly for environmental cleanup. The nanocomposites have proven to offer remarkable qualities as platforms for heavy metal detection sensing. Monitoring the water quality is one of the key concerns of researchers in the modern period. Heavy metal contamination is a significant issue and poses a risk to ecological preservation. Due to this, several efforts are being made in present to develop sensitive, quick, and selective sensors. Reversibility, high specificity, and sensitivity are three unique and intriguing characteristics of colorimetric sensors that have grown in popularity. The particular features of nanomaterials, such as those based on metal and metal oxide, polymers, and carbon, make them beneficial for cleaning up the environment. We examined the most recent (2010–2022) advancements in metal composites for the treatment of metal ions in contaminated water in this review study.

含重金属离子的污染已引起广泛关注。它给人类处境和环境系统带来了深思熟虑的风险。纳米技术可以控制、创建和测量分子和原子大小在 1 到 100 纳米之间的物体。它们的表面积与体积之比很高。这些是最实用的，并且是易于访问的原因，特别是对于环境清理。事实证明，纳米复合材料作为重金属检测传感平台具有卓越的品质。监测水质是现代研究人员关注的重点之一。重金属污染是一个重大问题，对生态保护构成威胁。因此，目前正在做出一些努力来开发灵敏、快速和选择性的传感器。可逆性，高特异性，和灵敏度是越来越受欢迎的比色传感器的三个独特而有趣的特性。纳米材料（例如基于金属和金属氧化物、聚合物和碳的材料）的特殊特性使其有利于清洁环境。在本综述研究中，我们研究了金属复合材料在处理受污染水中的金属离子方面的最新进展（2010-2022 年）。
