Abstract:
OBJECTIVE: To establish a method for the determination of the content of thiomersal in hepatitis B vaccine. METHODS: The content of thiomersal in hepatitis B vaccine was determined by flow injection-hydride generation atomic absorption spectrometry. The samples were treated by reflux digestion method with 4% sulphuric acid as medium,0.5% potassium borohydride as reducing agent,and 0.5% sulphuric acid as supporting liquid. RESULTS: The linear range of thiomersal was 5.0~100 ?g?L-1,with an average recovery rate of 100.6%(RSD=0.89%) and the lowest detection limit of 1.00 ?g?L-1. CONCLUSION: The method is simple,rapid and sensitive,and suitable for the determination of the content of thiomersal in hepatitis B vaccine.
