ABSTRACT
Objective:To improve the determination method for compound sodium acetate injection. Methods:Atomic absorption spectrophotometry ( AAS) was used to determine sodium chloride, calcium chloride and potassium chloride in compound sodium acetate injection. Results:The linear range of calcium ion, potassium ion and sodium ion was 9.124 ×10 -7-1.369 ×10 -5 g·ml-1(r =0.999 5),1.501 ×10 -7 ~4.504 ×10 -6 g·ml-1(r=0.999 2) and 7.500 ×10 -8-2.251 ×10 -6 g·ml-1(r=0.999 5), and the av-erage recovery was 100. 4%(RSD=1. 4%,n=9),102. 4%(RSD=1. 6%,n=9) and 100. 3% (RSD=1. 1%,n=9), respectively. Conclusion:The method is simple, accurate and reproducible, and can be used to control the quality of compound sodium acetate in-jection.
