Arginine accounts for about 6% in human hair, and there is almost
no loss of arginine in the mother liquor after extracting cystine.
Therefore, after the mother liquor is desalted, the arginine is
separated by exchange with a cation exchange resin. According to
the exchange capacity of the resin to arginine, as long as the
amount of the resin is controlled, the arginine can be exchanged
and exchanged without being exchanged with other amino acids. Then,
the arginine is eluted with an alkaline eluent, and the eluate is
concentrated under reduced pressure to obtain crystal arginine.
Suzhou Bojie Resin Technology Co., Ltd. provides arginine
extraction resin with high exchange capacity, fast adsorption
speed, stable physical and chemical properties, good mechanical
strength, convenient process operation, repeated use of resin after
regeneration, and good economic benefits.
