- 論文の詳細を見る
A preconcentration method for cadmium(II) in natural water based on synergistic extraction is described. Cadmium(II) is extracted as the ternary complex Cd(II)-dithizone-TOPO(trioctylphosphine oxide) from 2.5 dm^3 of a water sample into 25 cm^3 of carbon tetrachloride and back-extracted into 10 cm^3 of 0.2 mol dm^<-3> nitric acid. By using this method, cadmium(II) in natural water with levels below the ppb range could be determinedby flame atomic absorption spectrometry.
