Description
Summary:Nano zero-valent iron (nZVI) is a well-known and effective remediation agent for various water contaminants. However, the challenges associated with its application, such as agglomeration and difficulty in recovery, have limited its effectiveness in large-scale treatment processes. In recent years, the development of nZVI nanocomposites has shown promise in addressing these challenges, as they offer improved stability, reactivity, and recoverability. This paper reviews the latest advancements in nZVI nanocomposites for water treatment and discusses their potential for the sustainable remediation of various contaminants, including heavy metals, organic contaminants, and emerging contaminants. The potential applications, limitations, and future prospects of nZVI nanocomposites in water treatment are discussed in detail. Overall, the findings suggest that nZVI nanocomposites have significant potential for sustainable water treatment and can contribute to the development of cost-effective and environmentally friendly water treatment solutions.
