<b>Determination of trace amounts of zinc by flame atomic absorption spectrometry after separation and preconcentration onto modified natural analcime zeolite loaded 2,3,5,6-tetra(2-pyridyl)pyrazine</b>

Zinc ions were separated by solid phase extraction onto modified natural analcime zeolite loaded with 2,3,5,6-tetra(2-pyridyl)pyrazine (TPPZ). Extraction efficiency and the influence of sample matrix, flow rate, pH, and type and minimum amount of stripping eluent were investigated. Solutions of zinc...
