A Magnetic Adsorbent for the Removal of Cationic Dyes from Wastewater

In this article, a study was presented on the adsorption activity of a new nanocomposite particle Fe(3)O(4)@1, which was synthesized by combining [Cu(HL)(2)](2)H(2)[P(2)Mo(5)O(23)]·10H(2)O (1) (HL = 2-acetylpyridine semicarbazone) and Fe(3)O(4) nanoparticles. Transmission electron microscopy and X-r...

Sumario:In this article, a study was presented on the adsorption activity of a new nanocomposite particle Fe(3)O(4)@1, which was synthesized by combining [Cu(HL)(2)](2)H(2)[P(2)Mo(5)O(23)]·10H(2)O (1) (HL = 2-acetylpyridine semicarbazone) and Fe(3)O(4) nanoparticles. Transmission electron microscopy and X-ray powder diffraction analyses revealed that Fe(3)O(4)@1 possessed high crystallinity with an average particle size of 19.1 nm. The adsorption activity of the as-prepared Fe(3)O(4)@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(3)O(4)@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(3)O(4)@1. It was shown that Fe(3)O(4)@1 is a promising candidate material for adsorbing cationic dyes in aqueous media.
