Magnetic nanoparticles have good potential application in textile, environmental, and waste water treatment cause for their unique properties such as large surface areas, size and shape-dependent catalytic properties. Magnetic nanoparticles can be used alone or to be one of a mixed matrix membrane. Smaller particle size provides a higher reactivity. But toxicity, recovery, and stability of these particles are important, and surface modification of these magnetic nanoparticles can reduce these anxieties. The properties and application of these nanoparticles in the textile industry are discussed in this review paper.
