Using Polyaniline/Maghemit Magnetic Nanocomposite for Removal of Lead from Aqueous Solutions

Fatemeh Sabermahani; Leyli Irannejad; Nosrat Madadi Mahani

Volume 5, Issue 1 , March 2018, Pages 33-38

Abstract
    Polyaniline/maghemite magnetic nanocomposite (PANI/γ -Fe2O3 MNC) was used as active agents for removal of lead ions from aqueous media. Chemical co-precipitation method was used to prepare the maghemite nanoparticles. Subsequently, the MNC was synthesized through polymerization of aniline. ...  Read More
