摘要

Magnetic chromatograph is a techniques that use magnetic force to separate small particles. It is interesting because the magnetic column can be used repeatedly and does not produce secondary wastes. In order to increase the efficiency of the separation, the magnetic force is desired to be as large as possible. The magnetic force increases in proportion to the magnetic field gradient, and when the source of the magnetic force is a wire, the magnetic field gradient increases in inverse proportion to the diameter of the wire. Therefore, it is estimaled that an assembly of ferromagnetic nano-wires can produce large magnetic force. Anodized porous alumina has ordered and uniform nanometer-sized hole arrays. Various materials including ferromagnets, such as Fe, Ni and Co, can be easily electrodeposited from the bottoms of the holes, and the holes can be filled with nano-wires. These ferromagnetic wires have nano-meter sized diameters. Therefore, they are assumed to be able to produce strong magnetic force. We propose to apply ferromagnetic nano-wires in porous alumina arrays to magnetic force generators for magnetic chromatograph.
