1. Introduction

Introduction

Nanocomposites are composite materials consisting of nanoscale building blocks. They are gaining attention in water remediation because of their unique properties and potential applications. In water remediation, nanocomposites can be used for removing pollutants such as heavy metals, organic compounds, and microorganisms. They can also be used for water purification and treatment.

One common example of nanocomposites in water remediation is using metal oxide nanoparticles, such as iron oxide or titanium dioxide, in combination with a polymer matrix. These nanocomposites have a high surface area-to-volume ratio, which makes them highly effective for adsorbing pollutants from water.

Nanocomposites also offer advantages over traditional water remediation technologies because they are durable, reusable, and can be easily modified to target specific contaminants.

Nanocomposites Types

There are several types of nanocomposites that are used in various applications, including water remediation. Some of the most common types are:

  1. Polymer-based nanocomposites: These are composed of polymer matrix and nanoscale fillers such as clay, carbon nanotubes, or metal oxide nanoparticles. They are widely used in water treatment due to their high efficiency and low cost.

  2. Hybrid nanocomposites: These are made by combining two or more types of nanoscale building blocks, such as metal oxide nanoparticles and graphene, to form a composite material. Hybrid nanocomposites exhibit improved properties compared to their individual components.

  3. Inorganic-organic nanocomposites: These nanocomposites are made by combining inorganic materials such as metal oxides, silica, or zeolites with organic polymers. They are commonly used in water purification applications due to their ability to remove pollutants such as heavy metals and organic compounds.

  4. Magnetic nanocomposites: These are made by incorporating magnetic nanoparticles into a polymer matrix. They are used in water treatment applications due to their magnetic properties, which enable easy separation and recovery of the nanocomposites after use.

  5. Bio-based nanocomposites: These are made using biodegradable polymers and nanoscale building blocks such as cellulose or chitin nanofibers. They are used in water remediation applications due to their biocompatibility and environmentally friendly nature.
