Regarding the HONTA column for MA / Ln separation, the scheme for efficient Ln separation was examined from the results of the batch test, and the performance was confirmed by the column test. Considering that a flow in which only MA is selectively adsorbed on the HONTA column is appropriate, it was confirmed by a column test that the target flow can be achieved by washing and removing without adsorbing Ln.
