▼ [12a-N324-6] Magnetic Separation of Rare Earth Ions
キーワード：magnetic separation, rare rarth ion, Dy ion
Magnetic separation is a technique to separate mixed substances using a magnetic force. In this study, the target of magnetic separation was rare earth ions. Rare earth metals are indispensable for producing high-tech products and their demand is expected to increase hereafter. Magnetic separation is an effective technology for recycling them for stable supply.
From the above, we researched about magnetic separation experiment of rare earth ions in aqueous solution. the experimental system was constructed to obtain concentration changes from light interference fringes with a Mach-Zehnder interferometer. The changes of interference fringes corresponding to Dy ion concentration were observed and we confirmed the enrichment occurred 20s after the start of magnetic field application. We plan to quantify how much the concentration has changed by analyzing the interferograms.
