Abstract:
A rapid and sensitive methed for the determination of trace cadmium in environment water samples based on flowinjection on-line preconcentration on two-microcolumn system-flame atomic absorption spectrometry has been developed. The cadmium in samples was sequentially retained on two microcolumns with cation exchange resin and was eluted directly in the nebulizer by 1.5 mol x L(-1) HCl solution. The characteristic concentration (preconcentration time 1 min) for cadmium was 0.931 microg x L(-1). The relative standard deviation at the 5 microg x L(-1) level was 2.69% and the corresponding detection limit (3sigma) was 0.808 microg x L(-1). The method has been successfully applied to the determination of cadmium in water reference material GBW08608 and other water samples.
