【摘要】 用硝酸、高氯酸、过氧化氢(体积比3∶3∶4)作消解剂,采用微波消解处理样品,建立了电感耦合等离子体发射光谱法(ICP-AES)同时测定飞机草茎(主干和嫩枝)、根(主根和须根)及叶各部位中Ca、Mg、Na、Fe、Mn、Zn、Al、Ba、B、Cr、Cu、Sr、Ti 13种常量与微量元素含量.结果显示飞机草各部位元素分布有较大差异,大多数元素在根和叶中含量较多.更多还原

【Abstract】 A method based on microwave digestion and inductively coupled plasma-atomic emission spectrometry(ICP-AES)was established for simultaneous determination of thirteen constant and trace elements(Ca,Mg,Na,Fe,Mn,Zn,Al,Ba,B,Cr,Cu,Sr and Ti)in stems,roots and leaves of Eupatorium odoratum L..Samples were digested in microwaved mixture of HNO3,HClO4and H2O2(3∶3∶4).Optimal conditions for microwave digestion and working parameter of ICP-AES were obtained.It was found that these elements were present in plant parts at different levels,most were present more in roots and in leaves.更多还原
