摘要：

Positively charged alumina surfaces were coated with sodium dodecyl sulfate, into which 1-nitroso-2-naphthol was immobilized. The alumina particles were effectively used for the collection of nanogram amounts of cobalt(II) from aqueous solutions of pH 1 - 2.5. The method has been applied to the electrothermal AAS determination of cobalt in high-purity zinc metal.
