摘要
This paper reports a simple and efficient chemical method to decorate multi-walled carbon nano- tubes（MWCNTs） with iron oxide nanoparticles. The TEM, FTIR, Raman and UV analysis demonstrate that iron oxide nanoparticles were well deposited on the outer walls of MWCNTs. The size of the nanoparticles ranges from 30 to 50 nm. The sorption property of MWCNTs/Fe3O4 composites for the removal of 2,4-dichlorophenol（2,4-DCP） and Cu2＋ ions from aqueous solution was explored. The results present that MWCNTs decorated with Fe3O4 possessed higher sorption capability for removing 2,4-DCP and Cu2＋ ions, which favour the highly potential applications for pollutants removal from water.
