This paper presents an experimental investigation on the crystallization thermodynamics of coba-lamine by means of laser.The influences of temperature and different solvents on the solubility and supersolubility are studied.The metastable zone is also measured.It shows that the metastable zone width becomes wider with decreasing the proportion of acetone.The influences of four typical ionic impurities(Na+,Mg2+,Ca2+ and Fe3+) on cobalamine crystallization are studied.Some of crystallization products become fragmentation and agglomeration with ionic impurities existence.The surface configuration has been characterized by SEM.As a result,it shows that Fe3+ and Mg2+ have more significant effects than Na+ and Ca2+.
