Abstract：In this paper, a series of chitosan-arginine(CS-Arg) with different substitution degrees were prepared by changing the molar ratio of arginine to chitosan.Chemical structure and morphology of CS-Arg were characterized through FTIR, TG and elemental analysis.CS-Arg nanofibers(CANFs) were successfully fabricated via solution blowing of CS-Arg and polylactic acid mixed.It was evaluated the adsorption characteristic of CANFs for bovine serum albumin(BSA).The adsorption capacity of A4(CANFs-4)affinity membrane for BSA was the best, which reached to 379.43 mg/g.
