超顺磁性Fe3 O4微粒的尺寸调控与磁性回收
Size-Controlled Synthesis and Magnetite Recovery of Superparamagnetic Fe3 O4 Microparticles
摘要
Abstract
Fe3 O4 microparticles of different size were synthesized by a novel solvothermal method,using ethylene glycol as solvent.It is found that the nucleation and growth of Fe3 O4 can be effectively con-trolled through adjusting the concentrations of water,polyethylene glycol 20000,and iron ion,which cre-ates the possibility of controlling the size of Fe3 O4 in a wide range effectively.Besides,Fe3 O4 microparti-cle of larger size exhibits more excellent magnetic recycling property.As discussed above,the effective control of Fe3 O4 particle is very important to expand its application in magnetite recovery of nanomateri-als.关键词
