[Determination of microelements in different parts of Limonium bicolor by FAAS].
Eight microelements in the flower, stem, leaf and root of limonium bicolor were determined by FAAS. Different parts of the powder were digested with HNO3-HClO4 mixed acid (4+1) before the determination. Work conditions, accuracy and precision of the method were studied. The experimental results show that the recovery (n = 7) is 99.3%-105.3%, while RSD (n = 7) is 0.34%-1.04%. The content of each microelement in the different parts of limonium bicolor is not the same. For the flower: Na>K>Mg>Ca>Fe>Zn>Co>Cu, stem: K>Mg>Ca>Na>Fe>Zn>Cu>Co, leaf: K>Mg>Ca>Na>Fe>Zn>Co>Cu, and root: K>Mg>Na>Fe>Ca>Zn>Cu>Co, but the contents of K, Mg, Cu, Na and Fe in all different parts of limonium bicolor are relatively high. The method has good precision and accuracy so that it is able to meet the requirements for analysis.
