| Abstract: | This paper aims to determine the content of microelements of iron, zinc, strontium, copper, manganese and nickel through ICP-AES method under the optimal condition of instrumental analysis. The detection limits for microelements were 0.002rag/L, 0.005mg/L, 0.000 lmg/L, 0.002mg/L, 0.0005mg/L, 0.003mg/L, 0.008mg/L, 0.003mg/L, and 0.005mg/L, respectively. RSD was in the range of 0.38%-0.79% and recovery rate in the range from 93.8%- 104.3%. The proposed method was proved to be simple, rapid and accurate, and the result was satisfactory. |
