| Abstract: | A Graphite Furnace Atomic Absorption Spectrometry (GFAAS) method for direct determina- tion of trace cyanocobalamin in folic acid and cyanocobalamin injection is introduced herein. The method is based on the direct determination of cobalt in cyanocobalamin,being sensitive, rapid and free of interference.It is easy to operate without separation. The average recovery of cyanocobalamin reaches 100. 9% and the coefficient of variation is 1. 6%. |
