| 摘 要： | 研究了用微波消解ICP—AES对玫瑰花、金银花中Cu、Zn、Fe、Mn、Na、Ca6种元素进行测定的方法，优化了ICP—AES的工作参数，考察了消解液的种类及用量对测定结果的影响，选择玫瑰花的消解液为V（HNO，）＋V（HClO4）：5＋3，金银花的消解液为V（HNO，）＋V（HClO4）=10＋3。结果表明，6种元素的检出限在0．005～0．021μg／mL之间，相对标准偏差（RSD）均小于8％，回收率为95．6％～103．9％，该法用于玫瑰花、金银花中元素的测定，结果令人满意。金银花、玫瑰花中含有丰富的微量元素，对人体健康十分有益。

| Abstract: | The method to determine copper, zinc, iron, manganese, calcium, sodium in Rose and Honeysuckle was investigated by microwave digestion and ICP - AES. Operating parameter of ICP - AES was optimized and the influence of digestion solution＇s kind and dosage on the determination results was investigated. The result showed that the best sensitivity when we seleeeted V（HNO3） ＋ V（ HC104） = 5 ＋ 3, V（ HNO3 ） ＋ V（HC1Q） = 10 ＋ 3 as digestion solution in this experiment. The detection limits of this six elements were 0. 005 - 0. 021 μg/mL. All the relative standard deviation （RSD） were less than 8%. The coefficient of recovery is 96.4% - 104. 2%. The method was used to determine element in Rose and Honeysuckle with satisfactory results. |
