ABSTRACT
Since magnetic separation was rst described for separating iron minerals by William Fullarton, it has aroused a continuously increasing worldwide concern in areas ranging from adsorption to biotechnology [1-5]. In an effort to combat the problem of water pollution, the processes based on magnetic nanomaterials (MNMs) have been considered promising options for reducing contaminants owing to their rapid, low-cost, and highly efcient
