| Abstract: | Objective: To develop a method for determining the content of mercury contained in Yuhong ointment.Method: The wet catalytic digestion method was adopted for the pretreatment,and the mercury content in Yuhong ointment was determined by hydride generation-atomic absorption spectrometry(HG-AAS).Result: The mercury showed a good linear relation in the range from 2 to 20 μg·L-1,with the average recovery of 104.27% and RSD of 3.37%.The RSD for real sample repeated measurement was determined to be 8.4%.The mercury content in Yuhong ointment was detected in range from 0.7 to 1.5 mg·g-1.Conclusion: The proposed method is accurate,highly reproducible and it can be used to control mercury content of Yuhong ointment. |
