Application of Sulfur-Modified Magnetic Nanoparticles for Cadmium Removal from Aqueous Solutions

Shahryar Jafarinejad; Mohammad Faraji; Zohreh Norouz; Javad Mokhtari-Aliabad

Volume 3, Issue 1 , January 2018, Pages 58-69

https://doi.org/10.22090/jwent.2018.01.006

Abstract
  Even at low levels, heavy metals are toxic and can damage living things. They do not break down or decompose and tend to build up in plants, animals, and people causing health concerns. Magnetic nanoparticles (MNPs) can be considered as potential adsorbents for the removal of cadmium (Cd2+) from aqueous ...  Read More
