title: Simultaneous determination of Co, Al and Fe by HR CS-GFAAS.
abstract: In this study, simultaneous determination of Al, Co and Fe by high resolution continuum source graphite furnace atomic absorption spectrometer (HR-CS GFAAS) was performed satisfactorily. For this purpose, the spectral area between 237.148 and 237.403 was monitored and Al, Co and Fe absorbances were detected at absorption lines, 237.312 nm, 237.185+237.283+237.386 nm and 237.362 nm, respectively. The characteristic concentrations and LOD values for the working wavelengths of Co, Al, and Fe were 48.0, 6.00, 54.0 µg L(-1), and 12.0, 14.0, 16.0 µg L(-1), respectively. The linear working ranges were spread over 0.01-10, 0.05-2.5 and 0.05-10 mg L(-1) for Co, Al, and Fe, respectively. In the end, Al, Co and Fe in several certificated reference materials and waste water samples were determined satisfactorily by HR-CS GFAAS. With this proposed method a fast and straightforward simultaneous determination by HR CS AAS shown as possible.
