摘要
目的:研究天山堇菜中的微量元素,建立最佳测定条件。方法:以湿法消解样品,原子吸收法测定了8种元素,分别以氯化锶、磷酸二氢铵、磷酸二氢铵-EDTA-硫脲为基体改进剂,进行了回收率试验,并以标准物质灌木枝叶进行比较测定。结果:测定出天山堇菜中8种元素的含量,优化出最佳测定条件及基体改进剂。结论:天山堇菜中含有较高对人体有益的微量元素,本测定方法具有很好的准确度和精密度。
Objective：To study microelements in Viola tianshanica Maxim. and finding the optimum measurement condition. Methods： Viola tianshanica Maxim. were treated by nitric acid and perchloric acid. Eight elements were detected by atomic absorption spectrometry. SrCl2, NH4H2PO4, NH4H2PO4 - EDTA - NH2CSNH2 were taken as matrix modifier. Recovery test and contrast test were carried out with standard sample GBW07602 bush twigs and leaves. Results： The content of eight elements in Viola tianshanica Maxim. was obtained and the optimum instrument parameters and matrix modifier were selected. Conclusion：There are rich useful microelements for human body in Viola tianshanica Maxim.. The method has satisfactory precision and accuracy.
