Abstract

The traditional Mongolia medicine named wu lan-3 was digested by microwave,and the amounts of zinc and ferrum in the samples were determined by FAAS method under the optimal experimental conditions.The characteristic concentrations for Fe and Zn are 0.18 and 0.051(μg/mL/1%) with the average recoveries of 98.5%—101.3% and 98.0%—102.5% and RSD(%) of 0.40% and 1.60%,respectively.The method is simple and the result are satisfactory.
