| Abstract: | Sample of sowthistle herb was digested with HNO3 and the microamounts of Fe、Zn、Ca、Mg insowthistle herb were determined by FAAS,The results showed that four trace elements coexisted in sowthistle herb did not interfere with each other under the optimized conditions.The relative standard deviation was 1.3%～3.0%,and the addition standard recovery was 92.0%～103.3%. |
