摘要(Abstract):

[Objective] To establish an atomic absorption spectrophotometry (AAS) method for determination of iron black in RADIX POLYGONI MULTIFLORI PREPARATA CUM SUCCO GLYCINES SOTAE. [Method] Through ferric salt chemical reaction, the content of iron black was determined by AAS with standard solution of iron as control. Then experimental results were verified by ICP-MS. [Result] AAS method was specific for determining the content of iron black in RADIX POLYGONI MULTIFLORI PREPARATA CUM SUCCO GLYCINES SOTAE. The calibration curve of iron atoms showed good linearity in the range of 1.5 to 15 μg/ml. The average recovery rate was 96.21% with RSD of 1.3% (n=6). And the experimental data were similar to that determined by ICP-MS. [Conclusion] Some tested samples of RADIX POLYGONI MULTIFLORI PREPARATA CUM SUCCO GLYCINES SOTAE in the market contain chemical dye iron black. AAS is reliable, simple and easy, which can be used for determining the content of iron black.
