Embodiment 1
[0055] use figure 2 In the process shown, the lysine-containing solution is contacted with multiple groups of cation-exchange resin column groups for ion-exchange chromatographic separation, and each group of cation-exchange resin column groups sequentially and cyclically passes through the adsorption zone, backfill zone, alkali conduction zone and regeneration zone , so that the cation exchange resin column group sequentially and cyclically performs exchange adsorption, purification and re-adsorption, desorption and regeneration, and obtains an eluent after desorption, wherein,
[0056] Three sets of cation exchange resin columns connected in series are in the adsorption area at the same time, each set of cation exchange resin columns is composed of 4 parallel cation exchange resin columns, and the cation exchange resin in the cation exchange resin column is WD-2 type lysine Special strong acid type cation exchange resin, the total exchange capacity of the cation exchange re...
