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