| Abstract: | old in Ores samples was determined by flame atomic absorption spectrometry following on-line preconcentration on a microcolumn packed with polyurethane foam in a flow-injection sys-tem. An enrichment factor of 50 was obtained at a sample flow rate of 16ml/min. The method hasbeen applied to the determination of Au in ores samples with satisfactory results. |
