目的: 建立同时检测清热解毒类中草药样品中Cu、Fe、Zn、Mn、Na、K、Ca、Mg、Cr、Ni、Pb、Se、As、Cd等14种元素的含量的分析方法。 方法: 用微波消解法对清热解毒类中草药样品进行消化,以电感耦合等离子体发射光谱仪(ICP-AES)检测样品中14种元素的含量,并优化微波处理条件。 结果: 清热解毒类中草药中含有丰富的对人体有益的常微量元素。 结论: 采用微波消解技术和ICP-AES相结合检测常微量元素具有省时、省力、环境污染小,测定结果快速、准确等优点。
Objective: To establish a method for simultaneously determining fourteen constant and trace element contents of Cu,Fe,Zn,Mn,Na,K,Ca,Mg,Cr,Ni,Pb,Se,As and Cd in six herbal drugs. Methods: Microwave digestion procedure was applied under optimized conditions for digesting medicinal herbs.Element concentrations were determined by ICP-AES. Results: The result indicated that the herbal drugs were abundant in constant and trace element contents in the human body. Conclusion: Conbining the microwave digestion technology with the ICP-AES,There were a lot of merits of time-saving,reduces effort,small environmental pollution,fast and accurate determination result in determining constant and trace elements.
