摘　　要：本文以甘草、陈皮和一含13味药的复方为对象,研究了所含痕量元素的形态分析方法。提出了初级和次级形态分析流程和相应的样品制备方法,用原子吸收法、离子色谱法等对上述样品中的Cu、Fe、Mn、Zn、Cr、Ni、Mo、Se、B、K、Ca、Mg、F^-、Cl^-、SO_4^(2-)、PO_4^(3-)以及NO_3^-进行测定,算出了有关元素在各样品中的提取率、浸留比等8种初级形态分析参数及颗粒吸附态、游离态等8种次级形态分布。Licorice root, dried tangerine peel and a prescription containing 13 diverse drugs were used as typical samples to study the methodology of speciation analysis of trace elements in the drugs. The scheme of primary and secondary level of the speciation analysis and corresponding methods of sample preparation were proposed. The results of the determination of 16 components, Cu, Fe, Mn, Zn, Cr,Mo,Se,B,K,Ca,Mg,F^- ,Cl^-, SO_4^(2-) and PO_4^(2-) (and NO_3^-) in above mentioned samples by means of AAS, HPLC,IC etc,are given. Eight parameters and eight species distributions of the primary and secondary-level speciation analysis,such as extractive rate,immerse-residue ratio, etc. and granule adsorbate, free ions content, etc. in the samples were calculated.
