Abstract
Abstract::
Nanoparticles are widely used in manufacturing, daily life applications, and other fields
because of their unique properties. However, the nanoparticles that end up in surface water are difficult
to break down naturally and cause environmental hazards that cannot be ignored. In this paper,
the migration mode of nanoparticles in the environment was proposed, and the factors affecting the
removal efficiency of nanoparticles mainly include ionic strength, natural organic matter, surface
properties, etc. The common methods for removing nanoparticles mainly include coagulation precipitation
methods, activated sludge methods, membrane filtration methods, and adsorption methods. In
addition, new technologies such as photothermal removal and electro-adsorption have also been applied
to remove nanoparticles in water. In future research, combining the advantages of different
removal methods and using different methods interactively to remove nanoparticles in water could
become a new research direction.
