摘　　要：本文报告了维生素 B12及注射液的原子吸收光谱测定法。方法的1%吸收浓度为0.07微克,回收率分别为99.10%和98.92%,在氯化钠介质中测定值的变异系数小于2.01%,并且稳定性优于分光光度法。AAS was used to determine vitamin B_(12) and its injection.The method is established with 1% absorption value of 0.07μg.Their rate of recoveries was respectively 99.10% and 98.92%, and the variation coefficients were less than 2.01% in sodium chloride solution.Further more this method was more stable than that of spectrophotometry for analysis of vitamin B_(12).
