| 中文摘要 | dispersive liquid-liquid microextraction (dllme) was combined with flow injection inductively coupled plasma mass spectrometry for simultaneous determination of cadmium, lead and bismuth in water samples. the metal elements were complexed with sodium diethyldithiocarbamate, and then the complexes were extracted into carbon tetrachloride by using dllme. under the optimized conditions, the enrichment factors for cd, pb and bi are 460, 900 and 645 in 5 ml of a spiked water sample, respectively. the calibration graphs for the three metals are linear in the range of concentrations from < 10 ng l-1 to 1,000 ng l-1. the detection limits are 0.5 ng l-1, 1.6 ng l-1 and 4.7 ng l-1, respectively. the relative standard deviations for ten replicate measurements of 50 ng l-1 cadmium, lead and bismuth are 2.6%, 6.7%, and 4.9%, respectively, and the relative recoveries in various water samples at a spiking level of 50 ng l-1 range from 83.6% to 107.0%. |
