摘要：
Microscale preconcentration techniques using 1 to 10 milligrams of samples and microliter volumes of aqueous solutions and organic solvents are described for the determination of cadmium at the sub-ppm level in indium and nickel by graphite-furnace atomic absorption spectrometry. Several simple apparatus are devised to overcome operational difficulties resulting from the miniaturization and ensure the precision and accuracy of analytical results. Cadmium in the metals is heterogeneously distributed.
