Ferrite-Supported Nanocomposite Polymers for Emerging Organic and Inorganic Pollutants Removal from Wastewater: A Review

Abstract

In recent years, organic and inorganic contaminants in wastewater (heavy metals, halides, nutrients, dyes, and pathogenrelated water pollution) have become a major global problem. There were initially fewer toxins, but as a result of fast industrialization and other human activities, they have rapidly risen. In addition to producing a host of health problems and organ system failure in people, these toxins have had a disastrous effect on the ecological balance of plants, animals, and even microbes. On the basis of nanotechnology, several methods for decontaminating water that use nanoadsorbents and/or photocatalysts are being researched. Due to their improved physical and chemical characteristics, several research studies have focused on the elimination of organic and inorganic pollutants using ferritesupported nanocomposite polymers as possible affordable substitutes for currently employed materials. In this review, the toxicity of heavy metals and the different adsorption capabilities of metal-doped ferrites, which are employed to detect the pollutants in wastewater, are discussed in detail. Also, it provides various synthesis methods to produce ferrite-supported polymer-based nanocomposites and a current review of them with a special emphasis on their exceptional ability to remove organic and inorganic pollutants from wastewater. As a result, ferrite-supported polymer-based nanocomposites, which are also less expensive and swellable, can act as effective adsorbents for the removal of both organic and inorganic pollutants. It has outstanding performance for sizes between 10 and 30 nm.

An Updated Overview of Magnetic Composites for Water Decontamination

“…With these advantages in mind, several research studies have investigated the potential of ferrite-supported nanocomposite polymers for the removal of different contaminants from aqueous samples [ 143 ]. Specifically, various ferrites have been combined with polymers like chitosan [ 144 , 145 , 146 , 147 , 148 ], polypyrrole [ 149 ], polyaniline [ 150 ], polyimide [ 151 ], and polyvinyl alcohol [ 152 ] to offer effective solutions for the removal of organic [ 144 , 145 , 146 , 147 , 150 , 151 , 152 , 153 , 154 , 155 , 156 ] and inorganic [ 148 , 149 ] pollutants ( Table 4 ).…”
