Abstract:
With the combination of the microwave digestion and ICP-AES, and by optimizing the instrument conditions, the micro digestion-ICP-AES method for the determination of eight metal elements, Zn, Fe, Ca, Mn, K, Mg, Sr and Na, in Mongolian medicines has been established. This method works by determining one solution sample with many kinds of elements at one time. The average recovery of the method is between 92.2% and 113.3% and the RSD is between 0.4% and 3.2%. The accuracy and precision of the method was tested by comparing the values of GBW070602. The determination results were found to be basically consistent with the reference values, which means the test result is reliable.
