catena-Poly[[bis-(μ-2-formyl-6-meth-oxy-phenolato-1:2κO,O:O,O)copper(II)sodium]-μ-tetra-fluorido-borate-1:1'κF:F'].

In the title heterodinuclear complex, [CuNa(BF(4))(C(8)H(7)O(3))(2)](n), the Cu(II) ion is four-coordinated by four O atoms of two 2-formyl-6-meth-oxy-phenolate ligands, giving rise to a square-planar geometry. The Na(+) ion is six-coordinated by four O atoms from the two ligands and two F atoms of two tetra-fluoridoborate anions. The tetra-fluoridoborate anion links the Na(+) ions, forming a one-dimensional structure along [001].

In the title heterodinuclear complex, [CuNa(C(8)H(7)O(3))(2)(NO(3))](n), the Cu(II) ion is five-coordinated in a square-pyramidal arrangement by four atoms of two different ligand molecules in equatorial positions and one remote nitrate O atom in the apical position. The Na(+) ion is eight-coordinated by four ligand O atoms and four nitrate O atoms. The ligand links the Cu(II) and Na ions, forming a layered arrangement extending parallel to (001).

[Determination of arsenic, antimony, mercury and selenium in different parts of Acanthopanax senticosus harms by atomic fluorescence spectrometry].

A method for the determination of arsenic, antimony, mercury and selenium in different parts (root, stem, leaf and fruit) of acanthopanax senticosus harms using hydride generation atomic fluorescence spectrometry with microwave digestion was developed. Under the optimized experimental conditions, the concentration of arsenic, antimony, mercury and selenium showed a linear relationship with the fluorescence intensity. The detection limit of arsenic was 0.

[Determination of trace mercury in different sorts of Chinese herbs by atomic fluorescence spectrometry with microwave digestion].

A method for the determination of trace mercury in different sorts of Chinese herbs using hydride generation atomic fluorescence spectrometry under different microwave digestion conditions was developed. Under the optimized experimental conditions, the linear equation was I(F) = 809.1 x -3.
