“…410 These radionuclides are significant pollutants in nuclear power plants, agriculture, industries, and nuclear medicine. 411 The hazardousness of radioactive metal ions depends strongly on the halflife of the isotopes. For example, persistent radionuclides such as Cs-137 (half-life: 30.17 years), Sr-90 (half-life: 28 years), and Co-60 (half-life: 5.27 years) are the most dangerous metals for the environment since they are easily absorbed by organisms, highly adaptable, and soluble.…”

Heavy metal pollution results in enormous environmental impacts and significant human health problems. Because of their extreme toxicity and lack of biodegradability, heavy metal ions in water are considered problematic. Although the removal of various heavy metal ions from wastewater has been widely investigated, heavy metal contamination still requires effective and suitable remediation. With special attention on heavy metal removal, this study reviews recent advances, breakthroughs, and potential applications of various physical, chemical, and biological methods. Each treatment method has specific mechanisms of interaction with metal ions, which are described in this review. The discussion in this review leads to the conclusion that adsorption has the best potential which leads to the sustainable remediation of heavy metals. In summary, the review provides a new perspective on heavy metal reduction and encourages the development of innovative strategies for heavy metal removal. The main current problems and prospects in this field are highlighted in this review.

The disposal of multifarious contaminants in water resources poses a grave threat to the environment and health. Effective methods of treating and detecting these contaminants are crucial for ensuring access to clean and safe water. MXenes and MXene-derived materials have emerged as promising candidates for the design and development of novel techniques for water purification and sensing applications, by virtue of their unique characteristics. These nanomaterials offer highly versatile features such as amenability for surface functionalization, tunability of interlayer spacing, good electrical conductivity, favorable ion transport properties, and large specific surface area. Considering their immense potential, research on MXene-based technologies for combating the water pollution problem is still in its early phase. This review provides a critical overview and evaluation of the recent advances in MXenes and MXene-based composites for the remediation and detection of water contaminants. The progress in the application of MXene-based materials in water treatment techniques such as membrane separations, photocatalysis, and adsorption is summarized. The developments in MXene-based sensors relying on electrochemical, fluorescent, colorimetric, electrochemiluminescence, and surface plasmon resonance approaches for the detection of water pollutants are discussed. The challenges and future prospects in MXene-derived water-related technologies are identified to facilitate their practical implementation.

“…They only begin to degrade at very high temperatures and have a large specific surface area and high porosity, making them excellent adsorption materials. [22][23][24][25] To successfully prepare adsorbents with excellent adsorption properties, functional groups (nitrogen-rich groups and hydroxyl groups) with high affinity for metal ions should be synthesized. 26,27 The nitrogen-rich groups not only play a crucial role in the sequestration of metal elements but also have a certain role in the reduction process.…”
