| Abstract: | Objective： To establish a method for determination of trace barium in Creatine Phosphate Sodium for Injection by graphite furnace. Methods：Trace barium in Creatine Phosphate Sodium for Injection was determined by graphite furnace atomic absorption spectrometry. Restilts：The recovery was from 95.8% to 98.8%. The calibration curve was linear in the range of 0. 0 -300 μg·L^-1 for barium with r = 0. 999 5, and the relative standard deviation was less than 6. 3% （ n = 6）. Conclusion： The method is linear wide- ly with good precision, and the interference of memory for barium is cecluded. It has been successfully applied to the determination of barium in creatine phosphate sodium for injection. |
