摘要：

A new method of preconcentration with nanometer-strontium titanate immobilized on aluminum oxide (ASTO) combined with flame atomic absorption spectrometry (FAAS) was proposed for the determination of trace heavy metal ions, included Cu2+, Ni2+ and Ag+, in environmental water. The optimum experimental parameters for preconcentratiort of the heavy metals studied, such as pH, shaking time, eluent and coexisting ions, have been investigated. The results showed that Cu2+, Ni2+ and Ag+, could be quantitatively retained by the ASTO in the pH range of 5-8, and then eluted completely with 2 mol.L-1 HNO3. The detection limits of this method for Cu2+, Ni2+ and Ag+ were 0.031 mu g.L-1, 0.15 mu g.L(-1)and0.041 mu g.L-1 with an enrichment factor of 50, respectively. The method has been applied to the simultaneous determination of trace amounts of Cu2+, Ni2+ and Ag+ in environmental water, the recoveries were all in 95%-105%.
