Membranes for toxic- and heavy-metal removal

Since time ago, membranes have greatly attracted the attention of researchers for different types of water-treatment applications, such as wastewater treatment, water purification, removal of microorganisms, chemical compounds, and heavy metals. Nowadays, one of the current challenges of research community definitely deals with the removal of toxic and heavy metals from water. In this regard, the current chapter provides enough inputs about the current advances and approaches of the use of membranes for such removal task, thereby addressing the highlighted literature survey of using polymeric and nanocomposite membranes for heavy-metal removal. Moreover, it gives up-to-date information related to those novel nanocomposite membranes and their contribution for water-treatment applications.
