Facile synthesis and functionalization of hyperbranched polyglycerol capped magnetic Fe3O4 nanoparticles for efficient dye removal
چکیده انگلیسی


• One-step synthesis of multihydroxy Fe3O4/HPG nanoparticle is reported.
• The Fe3O4/HPG shows uniform size, excellent water-dispersibility and magnetic property.
• The surface property of Fe3O4/HPG nanoparticle can be readily tailored.
• Tailoring the surface of Fe3O4/HPG to afford multicarboxylic Fe3O4/HPG-COOH is reported.
• The Fe3O4/HPG-COOH can work as a high-performance magnetic adsorbent toward cationic dyes.

A straightforward approach for fabricating multihydroxy hyperbranched polyglycerol (HPG) capped Fe3O4 (Fe3O4/HPG) nanoparticles is reported. The obtained Fe3O4/HPG nanoparticles with numerous surface hydroxyl groups show uniform size and shape, excellent water-dispersibility, and strong magnetic property. The surface property of Fe3O4/HPG nanoparticles can be readily tailored as confirmed by preparing multicarboxylic Fe3O4/HPG-COOH nanoparticles in this paper. On the basis of their excellent magnetic performance and multiple negatively charged carboxylic groups, the Fe3O4/HPG-COOH nanoparticles can be utilized as an efficient adsorbent to remove cationic dyes from water. Moreover, they can be regenerated and reused for several times without compromise of adsorption efficiency.
