| Abstract: | Trace cadmium pre-concentrated with modified zeolite in the Yangtze River water samples were determined by flame atomic absorption spectrometry. By optimizing process of enrichment and elution and elimi- nating influence of interference ions, the results showed good linearity ranging from 0 Ixg to 4.00 trg; detection limits 0. 214 μg/L; RSD of parallel Yangtze River water samples 1.8% ; and spiked recoveries between 99.0% and 104%. |
