Abstract: Threekinds of chelating cellulose filters were prepared and ten trace elements were preconcentrated simultaneously on the microcolumn that was filled with the chelating cellulose filters.Alkali and alkaline earth metal ions were quantitatively separated as matrix elements at the selected pH values.The microcolumn has high enrichment factors and recoveries.
