A Magnetic Adsorbent for the Removal of Cationic Dyes from Wastewater.

ABSTRACT: In this article, a study was presented on the adsorption activity of a new nanocomposite particle Fe?O?@1, which was synthesized by combining [Cu(HL)?]?H?[P?Mo?O23]·10H?O (1) (HL = 2-acetylpyridine semicarbazone) and Fe?O? nanoparticles. Transmission electron microscopy and X-ray powder diffraction analyses revealed that Fe?O?@1 possessed high crystallinity with an average particle size of 19.1 nm. The adsorption activity of the as-prepared Fe?O?@1 was investigated by photometrically monitoring the removal of methylene blue, rhodamine B, safranine T, gentian violet, fuchsin basic, and methyl orange from aqueous solutions. Significantly, we could easily separate Fe?O?@1 from the reaction media by applying an external magnet. Furthermore, the recycling performance was observed using methylene blue, revealing the recyclability and high stability of Fe?O?@1. It was shown that Fe?O?@1 is a promising candidate material for adsorbing cationic dyes in aqueous media.
