OPTIMIZATION OF FLAME ATOMIC ABSORPTION SPECTROM- ETRY WITH PRECONCENTRATION BY FLOW-INJECTION ON-LINE SORBENT EXTRACTION OF CADMIUM AND LEAD IN BIOLOGICAL MATERIALS
A flow-injection (FI) system with a minicolumn of bonded silica with octadecyl groups (C-18) to collect diethyldithiocarbamate complexes of Cd and Pb in reference solutions and in acid-digested hair and blood solutions was developed and evaluated by flame atomic absorption spectrometry (FAAS). The s...
