| Abstract: | A rapid and effective method to determine the Cd in Chinese medicine was introduced.Factors that may influence the effect of the microwave digestion were saw about.The operating conditions of GFSAS were optimized too.The determine limit,linear range of the method is 0.0119mg mL -1 ,0～2mg·mL -1 respectively.The recovery of sample determination ranges from 91.7%～104 3%. |
