摘要：

Mass transfer in liquid fluidized beds of magnetic ion exchange particles was studied under various conditions. In the system investigated magnetic stabilization mostly resulted in poorer mass transfer rates as compared to common fluidized beds of non-magnetic particles. This work shows that an uncritical evaluation of common fluidized-bed relationships for mass transfer in liquid MSFB can result in significant overestimates of bed performance, especially at high flow rates.
