摘要	A novel hydride generation system was developed for the simultaneous hydride generation of lead and cadmium, i.e., the system of K3Fe(CN)(6)-(NH4)(2)Ce(NO3)(6)-NaBH4-HCl, which no interfering effects from the hydride generation of the two species were identified. The mechanisms of the hydride generation process include the oxidation of Pb(II) by (NH4)(2)Ce(NO3)(6), meanwhile, the K3Fe(CN)(6) was used as a coordinating reagent to form a complex with Pb( W) which facilitates its ensuing hydride generation. Cadmium hydride generation follows the conventional process with (NH4)(2) Ce ( NO3)(6) serves as a sensitizer. A sequential injection-hydride generation-atomic fluorescence spectrometric procedure was developed for the simultaneous determination of lead and cadmium. When employing the following experimental parameters, i.e., 2% NaBH4-3% HCl -0. 6% K3Fe(CN)(6)-0.3% (NH4)(2)Ce(NO3)(6), a 500-mu L sampling volume at a flow rate of 125 mu L/s, the obtained linear ranges were 0.4-15 mu g/L (Pb) and 0.5-20 mu g/L (Cd) respectively, along with limits of detection of 0.09 mu g/L ( Pb)and 0.17 mu g/L (Cd). The RSDs of the procedure were derived as 0. 5 % (6. 0 mu g/L Pb, n = 9) and 1. 0 % (6. 0 mu g/L Cd, n = 9). The present procedure was applied for the determination of lead and cadmium in a certified reference material of water sample, GBW08608, a coastal sea water and a riverine water sample, with satisfactory spiking recoveries.
